***Introduction and Greetings***
[gold] Hi, I'm an old Fortran programmer trying to retread. I actually served time on the IBM punch card machines. I collect old Fortran77 books as a hobby. A lot of guys leaving work would give me their old Fortran77 books. On active, i had a large Fortran collection, almost a library. I would loan and check out Fortran77 books to other employees. Also I programmed a lot in Javascript. Mostly I work on TCL now because i am visually oriented and think that a gui can save a lot of time in engineering calculations.

[gold]6/2/2021. [How did you discover TCL/TK] '''????''' >>
----
[gold] About 1996, the Personal Computer PC on my desk, was replaced by a Sun Sparc 20 workstation. I was an engineer and mainly programming in Fortran 77. I had learned QuickBasic, Html,  Perl (Unix),  and also Javascript. Since the Sparc 20 interface was command line Unix, I looked around for a gui or gui language as an interface to the Sparc 20 workstation. I found Tool Control Language TCL fairly easy to mouse click and invoke executable icons on the Xwindows screen. I even had a gimpy trashcan icon on the screen. I showed my beginner TCL program to a co_worker and he said I had fairly imitated the the PC Windows icon system on a Sparc20 workstation. But this was only about 200 lines of beginner TCL code and fast as greased lightning on a Sparc20! How's that for a sales job on TCL? Then, I  wrote small slot calculators in TCL and Javascript on the Sparc20 behind a firewall, which were similar to my later pages on this wiki. Never forget the human brain evolved to hunt rabbits, not Unix critters and command lines. Your eyes and brain modeling/mapping of the outside stims are closer to a gui screen than one might think.

*** Calculator approaches in  TCL console guis for Windows10 ***
----
[gold] 2021-09-13. These small TCL graphical user interface guis presented in the wiki for Windows10 may seem trivial math to some, but I have submitted  4 or 5 TCLLIB  tickets to improve the TCLLIB math library. For example,  the  math and logic functions IsOdd, IsEven, IsNegative, IsPositive, figurative_numbers, twin_primes, and Quadratic_Equation_Solution_for_reals were not in the TCLLIB library, as near as I can tell. Maybe these logic functions on integers and  Quadratic_Equations on reals are trivial math, but these math functions and quadratic equations show up in some other math languages, offsite TCL programs, and even TCL WIKI pages. As discussion with [HE] implies, the main idea of TCL or other computer language is that other users can share the faster compiled code rather than homebrew functions. I am retired and since I do not have easy access to a UNIX machine anymore, the only course is to proof the TCL routines on a Windows10 PC with  ActiveState TCL.

Like the example of the Wikipedia, i think that an automated PDF dump of the individual TCL/WIKI pages would be a useful storage item, especially if the PDF included a rack of end attachment of the original unix/ascii text data for the unique WIKI table format and the TCL programs.

about a math problem. I would lead up and carefully explain this and that algebra proposition. But my sister would say " I just want the answer!" In most engineering problems, there is an advantage in finding the answer in an approximate solution, say slide rule accuracy or 4 significant places. For example, using the old slide rule, one would make a preliminary pencil calculation and approximate answer to set the decimal point, before using the slide rule accuracy to 4 significant places. If one thinks of TCL as primarily as a graphical gui language, then the one liners programs are best used to check the preliminary math concepts. One liners programs and initial console programs are often used to check the math concepts and generate testcases before loading the calculator gui shell. ---- In planning any software, it is advisable to gather a number of testcases to check the results of the graphical user interface gui program. The results of the testcases are estimated using the hand calculations and then checked in the TCL gui calculator. Pseudocode and equations are developed from the hand calculations and theory. One liners procedures and small console programs are written to check or proof the alternate subroutines or procedures, rather than keeping the unblessed code and comment lines in the main gui calculator. Finally the improved or alternate subroutines are loaded into the gui calculator. The TCL gui or slot calculator is effectively a shell program to input entries, host calculation routines, maintain housekeeping procedures, and display results. Additional significant figures are used to check the TCL calculator, not to infer the accuracy of inputs and product reports. ---- ***Reposted Tips from [AMG] & [GWM] & Wiki for One Liners Programs*** ---- The beginner TCL procedure on the pi circle constant was corrected to proc pi {} {expr acos(-1)} ;# [AMG]. One Liners Programs should avoid using temporary variables like {set temp 3.14:if {$temp=3.14} {return 1};return $temp}. Temporary variables may cause more time delay, more complication, and possible confusion to reader. The return value of a Tcl procedure is inherited from the return value of the last command to execute within that procedure. Therefore, many uses of the [return] command are redundant. If one insists on temporary variables, be aware that it is perfectly legal for a [proc] and a variable to have the same name. You could have said "`set pi [[pi]]`". For safety and efficiency, always be sure to [brace your expr-essions]! Heh, I neglected to brace my expression in [[pi]], but that's one of the extremely rare cases where it won't matter: no spaces, no substitutions. Bracing does two things: One, when the entire expression is a single word (single argument), it can be [bytecode]-compiled. Two, if substitutions are performed by [expr] only and not [Tcl] itself, [injection attack]s are prevented. Since the expr command has an internal if conditional, [?] in a?b:c sic, try using the internal if <[?]> in expr rather than a separate [IF]statement. Avoid using separate if statements and temporary variables for brevity. The [args] variable is also useful tool in one liners programs for inputting multiple data or lists of words. Another strategy is to keep track of possible error checks and testcases for low, middle, and high values over the range of operation of the oneliners program. An initial check for zero division or series start at one may be installed in the expr ? conditional. A simple credit for a one liner program may use a semicolon with comment sign <;#> at statement end, which should not degrade program execution. Using the [time] function in TCL will give even more insights into one liners programs, also see [Time]. In [One liners Programs Pie in the Sky], one can see the advice of [GWM] on the importance of timing your code and procedures. Usually, invoking math ops, TCLLIB library, and other precompiled libraries can save an average of 1/3 time over big data chores. The time savings are not always obvious on small quantities of data. Performance of one liners programs may suffer degradation due to lengthy recursion calls and limits on the number of procedure recursion calls. The shorter the script, the faster and more reliable is the script. Dependence on math operator notation, helper procedures, math check examples, degradation due to lengthy recursion calls, and special library functions should be noted in the comment lines. The examples on this wiki page include code lines that might be incompatible, inefficient, or redundant if installed in the same program. As discussed, the local math procedures in scripts and one-line procedures may not be as fast and efficient as importing [mathop] , [mathfunc], and [math], so check with the precompiled code in the TCL core and TCLLIB libraries first, then homebrew your one-line programs and scripts. ---- ***Flexible Push Button Operation in TCL calculator*** [gold] 10/7/2018. Technical note on TCL calculator buttons addressing the reference ASK12 of 2017-02-19 . Many complex math programs have either initialize, refresh, or reset routines to force correct behavior, using calculator buttons. Of course, a very good feature of TCL is that new variables as number types do not have to be initialized prior to use. Repeating, setting a new number variable to 0 or 1 is not necessary prior to using the variable. I confess that habits brought from prior learned languages and 40 years ago are hard to change. Most of my gui programs on this wiki have a flexible button procedure (on changing labels and resetting variables prior to calculations). Where the program defaults are recalled, canvas colors/features/variables/clear displays are reset prior to ( in push button list) calculation. The buttons on the calculator are not limited to a single action proc or single shot. A button command may call multiple statements and procs like ::ttk::button .test4 -text "Test_wild_case3" -command {clearx; refresh_canvas_x .cv; fillup 120. 12.0 15.0 1. 1. 1. 1. 104.0; set global_variable 9999.;solve_routine;printout_routine;# need semicolons here; exit}. This is effectively a separate program or subprogram installed as list of procedures in a button. ---- The TCL language is very flexible, and as experiments, the button may invoke a do while routine to call the listed button procs multiple times like the infinite repeater (SiFi). The button may invoke command and call procedures for a random number of times and random solutions, like nerve and muscle firings from the human brain in thought and speech (not SiFi). For cosmetics, the button may set colors, frame width, canvas objects, and variables with the random proc lpick from RS on the wiki. As long as duplicate frames, duplicate canvas, pack managers, and channels are not confused reference the original program, one can load secondary and entire procs into the button list. Returning to the conventional use of resetting variables, the button refresh and initialize tactic should work across the TCL versions, at least in the versions tested (TCL8.5, and TCL8.6). ---- Most of the testcases involve experiments or models, using assumptions, and rules of thumb. For the push buttons in the TCL calculator, the recommended procedure is push testcase and fill frame, change first three entries etc, push solve, and then push report. Report allows copy and paste from console to conventional texteditor. For testcases in a computer session, the TCL calculator increments a new testcase number internally, eg. TC(1), TC(2) , TC(3) , TC(N). The testcase number is internal to the calculator and will not be printed until the report button is pushed for the current result numbers. The current result numbers should be cleared either on the clear button or on the next solve button. ---- ---- *** 2021 Newsflash, TCLLIB has twin primes and cousin primes routines in TCLLIB:math ticket pipeline *** ---- [gold] 5/13/2021. ---- closer: arjenmarkus [AM] ---- Emailed icomment from [AM]: I used the sample code to create two new procedures: ====== listPrimePairs listPrimeProgressions ====== The first proc '''listPrimePairs''' returns a list of pairs of primes that differ by a given number and the second proc '''listPrimeProgressions ''' returns a list of arithmetic progressions of primes that differ by the given number. ----

[gold]9/22/2021 I recently installed ActiveState TCL or ActiveTCL on Windows10. I have been working with ticket additions to tcllib math files. Maybe I am wrong, but the ActiveState installer from the ActiveState website (9/22/2021} installs the '''old Tcllilb content (Tcllib (tcllib-1.18) of three years ago in 2019'''. I tried installing the current library content from the https://sourceforge.net/projects/tcllib/ plus https://www.tcl.tk/software/tcllib/. It looks like the '''new content Tcllib tcllib-1.20''' is present now, on my local ActiveTCL copy. This installation is very tricky for a 70+ year old novice with bad eyes. And I am not sure that I installed '''tcllib-1.20''' right. Thank You

*** Use of Global Variables in TCL GUIS*** ---- [gold] 12Dec2018. Global variables, regular expressions, and namespaces are considered advanced features of the Tool Control Language (TCL), according to Brent Welch in Practical Programming in TCL and TK. If global variables are an advanced feature of TCL, as indexed and taught after the beginner TCL topics in most TCL textbooks, then reasonably the use of global variables should be explored and discussed on the wiki. After a number of searches on the wiki and reference books, the topics of regular expressions and namespaces are adequately explored on the wiki and available textbooks. In opinion, the use of global variables in TCL programs should not be restricted to a narrow viewpoint, and the use of global variables could be a very rich vein of interest for the advanced student of programming. As an engineer with 35 years experience in Fortran, Basic, Javascript, and other computer languages, the author is familiar with self-appointed gatekeepers and the other anonymous ad hominem methods of NDH. NDH means “not done here”, “not done here in our shop”, or “not done here in my programming style”. Global variables in TCL are equivalent to the common variable statements in Fortran and Basic. The use of global variables might be called “sideloading" for data subroutines. Ref Fortran77, the large number crunching programs with 2E5+ statements in Fortran used global variables or common variable declarations as an alternate way or “programming style” to transfer or sideload information between subroutines. The other data transfer method for subroutines was discussed by Brent Welch etc in the proc command arguments or top loading in the introductory or beginner TCL material. ---- [gold] 12Dec2018. Of course, each alternate way of data information transfer in toploading and sideloading data subroutines has its own advantages and disadvantages. As most TCL users know, TCL tends to be a more compact language than Fortran77. However, the global declarations in the small TCL graphical user interface guis written for numerical analysis on this wiki have exactly the same common variable structure and same program organization as the giant Fortran number crunchers. ---- [gold] 12Dec2018. There are two alternate methods of loading TCL subroutines, known as proc arguments (top loading) and global variables (side loading). In engineering terms, the TCL global variable methods and the Fortran common variables are an economy of scale for large programs. In other words, top loading a data subroutine for a small program with a limited number of variables and a limited number of subroutines is about as efficient as global variables (side loading). When a large program has the number of variables approaching 25 variables and the total number of subroutines approach 20 subroutines, then global variables or common variables become an more attractive alternative data transfer between subroutines and a more efficient use of the programmer's time. This principle is independent of language type, and equally true for the TCL, Fortran, and other computer languages. For example, many scientific Fortran programs had a specialized subroutine for constants, including the gravity constant, speed of light, etc. If the gravity constant was used in 15 subroutines, it was easier to declare the gravity constant as a common variable in a constants subroutine, and then make a one time change in the value of gravity constant in one subroutine of constants than making the same change for the gravity constant in 15 subroutines. If one knows than the sequence of slot variables {$side1,$side2,$side3...$side8...$side_N} and other constants are TCL global variables throughout the subroutines, one can easily refer to these global values in a specialized printout report subroutine. One can also load these global values in formulas for printout and separate calculations on the fly. For a side loading example in a new subroutine, proc newby {} {global side1 side2 side3; puts <* $side1 $side2 $side3>;return <+ $side1 $side2 $side3>}. The alternative top loading would be proc newby {side1 side2 side3} { puts <* $side1 $side2 $side3>;return <+ $side1 $side2 $side3>}. Both subroutine methods work for small TCL programs with the roughly same amount of typing. Remember in top loading, one would have to make other changes in the invoking statement or proc argument statement for the subroutine. One might point out that loading more than 25 variables in either an invoking statement or proc statement is not a trivial exercise to kept correct and cued properly. For another example, a specialized subroutine for printing out variables might use s set of global variables as proc printout {} { global side1 side2 side3; puts $side1; puts $side2; pouts <* side1 side2 side3>; puts "conversion to centimeters"; puts <* $side1_inches 2.54 >; }. A specialized printout subroutine with globals previously declared is faster in development and checking numeric formulas in experience, especially where conversion of units like inches and centimeters is useful for checking the results of the program in older textbook problems. ---- In opinion, a set of the same global statements in numerous routines are easier to keep organized. The condition of using global variables in method is that the user understands that not all variables are invoked over all the numerous subroutines. Therefore, in the case of multiple variables > 25 and multiple subroutines >20 in a large program, changing a constant variable in a large number of subroutines, little to do in the proc argument statements and invoking the subroutines, and the availability of the global variables throughout the program means less time spent on changes for the programmer. For terms of TCL presentation on the wiki, the slot variables could be changed inside the subroutine to recognizable names in variables for the calculations and quicker comprehension of the reader. In opinion, global variables are a more efficient use of the programmers time for a quick assembly of a working gui or installing a new working subroutine in a large TCL program. ---- [gold] 12Dec2018. The author is still learning TCL. These small TCL graphical user interface guis presented in the wiki have gone through an evolution of about twenty years, including numerous unpublished Javascript and TCL guis behind a firewall before joining the wiki. The suggestions from the wiki members have been of great help and these TCL guis have continued to improve. The guis are experimental numerical analysis in nature, and not every early TCL gui or program written over the twenty year period has the same global variable features, structured programming, or beauty spots of the TCL gui genre. The author keeps hearing that TCL is not a number crunching language or an outdated language from non-users. But in the instance of the TCL global variables, the TCL globals have the equivalence of the common statements and common variables in the data subroutines of giant Fortran number crunchers. ---- ---- *** Maybe partially solved, trouble accessing the TCL WIKI from USA on some restaurant WIFI's?*** [gold] 7/16/2020, Report so far, in coordination with ActiveState Support [email protected] ---- [gold] 08Jul2020.

Some of the original one liner commands were limited to a 60 character display on especially the early Basic terminals or to a 72 characters on the Fortran punched cards. Of course, the hit return to send, terminal flashing bulbs, and automatic answer back were silently understood as part or supporting the one liner program. Some of the line lengths in some computer languages were later extended to 410 lines and so on. The definition and use of the one liner program has been widened to include program source for any language that does something useful in one line. On batch programs, controlling and setting variable statements like RETURN, STOP, END, extra terminal prompts, and setting initial variables were used in Fortran systems. Of course, a very good feature of TCL is that new variables as number types do not have to be initialized prior to use and no subroutine RETURN and END statements are necessary, vis the older Fortran and Basic dogmas in moldy textbooks. Repeating, setting a new number variable to 0 or 1 is not necessary prior to using the variable. Since a partial and practical goal of computer programming is to produce human readable code, it is permissible on the published console batch programs here to retain some vestigial stages to aid human comprehension. ---- *** Timing Equivalent One Liners V2 *** ====== # pretty print from autoindent and ased editor # Timing Equivalent One Liners V2 # written on Windows 10 on eTCL # working under TCL version 8.6 # gold on TCL Club , 8/20/2020 # Ref.

AMG: The return value of a Tcl procedure is inherited from the return value of the last command to execute within that procedure. Therefore, many uses of the [return] command are redundant. For example, this procedure: proc anglecosa {a b c} {return [expr {($b*$b+$c*$c-$a*$a)/(2.*$b*$c)}]} can be written more simply: proc anglecosa {a b c} {expr {($b*$b+$c*$c-$a*$a)/(2.*$b*$c)}} Also, the conditional arguments to [if], [while], [for] are already expr-essions, so there's no need to nest a call to [expr]. For example, proc emmy2 {} {if {[expr {rand()}] <= 0.9} {return 1}} can be simplified quite a lot: proc emmy2 {} {if {rand() <= 0.9} {return 1}} #end of advice file ====== ---- scratch ---- ====== proc near_above_power_of_2x num {set pow 1; while {$pow<$num} {set pow [expr { $pow*2} ]}; return $pow} proc near_above_power_of_2 num {set pow 1; while {$pow<$num} {set pow [expr { $pow*2} ]}; return $pow} proc ld x "expr {log(\$x)/[expr log(2)]}" ;# RS [pow 2 [+ [int 2.8] 1]]= "8.0" proc zap x "[pow 2 [+ 1 [expr {log(\$x)/[expr log(2)]}]" proc zap x "pow 2 [+ [int 2.8] 1]" ====== ---- *** One Liners from www.codecodex.com/wiki *** ====== #under test from www.codecodex.com/wiki set lister { 1 2 4 5 6 7 8 9 10 } set s {starchild} package require struct::list proc reverseWords s {return [struct::list reverse [split $s]]} proc ! n {expr {$n<2? 1: $n*[!

Hence, the reasonable expectation or guess that the sequence will reduce in time. A rigorous result from Krasikov and Lagarias was that the number of N's that inside the region 1 to N that will coalesce or reduce to 1 is greater than '''expr { $N**.84} '''. Wulf Rehder reported that the bound on the Collatz_Sequences return to the original entry integer was a constant. The Rehder_limit_collatz_sequences constant is expr { (log(3)/log(2))/(log(3)/log(2)+1.)} returns 0.61314719276545848 or 61.3 percent. The complement or ''' < 1 - Rehder_limit> ''' is ''' 0.3868528072345415 or 38.6 percent '''. Meaning for long Collatz_Sequences and N>20 is that if one is at the Rehder_limit or return boundary of a long Collatz_Sequence, one can estimate the length of remaining steps of the tail. The Collatz_Sequence has 38.6 percent of tail left. It is curious that some of the TCLLIB Gauss_Legendre estimates for numbers of primes less than N are hovering over the lengths or step numbers of some Collatz_Sequences, N<50. Maybe numerical coincidence, but possibly these Gauss_Legendre procs could be hacked into predicting the length of some Collatz_Sequences. These results are not complete mathematical proofs of the Collatz Conjecture, but believe that the bounds will help characterize the envelope or trajectory of the longer Collatz_Sequences. ---- Lopsy posted that a number n has rough approximate ~log(n) Collatz steps to reach 1. Some Collatz_Sequences with 2 or more downward sequences and multiple breakpoints may be outliers to this ~log(n) formula. Solution for consecutive numbers with same Collatz length of steps starting at n, X = expr { log(n)* ( log(n))* ( log(log(n)))}, if consecutive numbers are present at number n. Have to check out ~log(n) Collatz steps. There are 7 steps for integer 10 whereasas numberPrimesLegendre 10 returns 7.677. There are 23 steps for integer 100 whereas numberPrimesLegendre 100 returns 27.73. ---- The Collatz_Sequence for 10 is '''< 10 5 16 8 4 2 1 >''' with 7 elements. By inspection, the Collatz_Sequence returns or drops below 10 between elements 3 and 4 or numbers 16 and 8 in the sequence. The Rehder_limit estimates the break point as ''' expr { 7. * .613 } ''' returns 4.291 , rounds to 4. The approximate number of terms or computer steps is 7. Using the Rehder_limit, Rehder_complement, and the expected tail of '''< 16 8 4 2 1 > ''', the approximate number of elements is estimated as ''' expr { ( 4.* .613 ) / .386 }''' returns 6.352, a little off. The Collatz_Sequence for 27 has 112 elements. Sequence for 27 has two breakpoints on elements 96 and 104. At 96, breaks between 46 and 23. The Rehder_limit estimates the break point as ''' expr { 112. * .613 } ''' returns 68.656 , rounds to 69. llength sequence_27_breakpoint returns 96. Sequence for 27 has 16 elements in tail. ---- ---- ====== # These statements should be pastable into the easy eye console. # ***** simple interest problems in TCL one liners procedures ***** # find simple interest amount from 3 entries as < principal interest years > proc simple_interest_amount { principal interest years } { expr { ($principal*1.)*(1.+$years*$interest )}} # Usage simple_interest_amount 5000. .05 7. returns 6750.0 # find simple interest principal from 3 entries as < amount interest years > proc simple_interest_principal { amount interest years } { expr { ($amount*1.)/(1.+$years*$interest )}} # Usage simple_interest_principal 6750.0 .05 7. returns 5000.0 # find simple interest rate from 3 entries as < amount principal years > proc simple_interest_rate { amount principal years } { expr { ((($amount*1.)/$principal)-1.)/$years }} # Usage simple_interest_rate 6750.0 5000. 7. returns 0.05 # find years of simple interest from 3 entries as < amount principal interest > proc simple_interest_years { amount principal interest } { expr { ((($amount*1.)/$principal)-1.)/$interest }} # Usage simple_interest_years 6750.0 5000. .05 returns 7.0 # ****** compound interest problems in TCL one liners procedures ****** # find compound interest amount from 4 entries as < principal interest years compounding_times_per_year > # cd is compounding times per year, usually 4 quarters or 12 months proc compound_interest_amount { principal interest years cd } { expr { ($principal*1.)*((1.+( $interest /$cd))**($years*$cd))}} # Usage compound_interest_amount 5000 .05 7 12 retuRns 7090.180 # find compound interest principal from 4 entries as < amount interest years cd > # cd is compounding times per year, usually 4 quarters or 12 months proc compound_interest_principal { amount interest years cd } { expr { $amount*( 1. +(($interest*1.)/$cd ) )**(-1.*$cd*$years)}} # Usage compound_interest_principal 7090.180 0.05 7 12 returns 4999.997, rounds to 5000. # find interest in compound interest from 4 entries as < amount principal years cd > # cd is compounding times per year, usually 4 quarters or 12 months proc compound_interest_interest { amount principal years cd } { expr { $cd*((($amount*1.0)/$principal)**(1./($cd*$years))-1.)}} # Usage compound_interest_interest 7090.180 5000. 7 12 returns 0.049, rounds to 0.05 # find years of compound interest from 4 entries as < amount principal interest cd> proc compound_interest_years { amount principal interest cd } { expr { (log10 (($amount*1.0)/$principal)) / ($cd*log10(1.+(($interest*1.)/$cd) ) ) }} # Usage compound_interest_years 7090.180 5000. 0.05 12 returns 6.99, rounds to 7 years # ******** continuous_compounding ******* based on exponential formulas and natural log. proc amount_continuous_compounding { principal interest years } { expr { $principal* exp ( $interest*$years*1. ) }} # Usage amount_continuous_compounding 5000. 0.05 7 returns 7095.3377 proc principal_continuous_compounding { amount interest years } { expr { $amount * exp ( $interest*$years* -1. ) }} #Usage principal_continuous_compounding 7095.33 0.05 7. returns 4999.994, rounds to 5000. proc interest_continuous_compounding { amount principal years } { expr { (log ( ($amount*1.) /$principal )) / ($years * log (exp(1.) ) ) }} # Usage interest_continuous_compounding 7095.33 5000. 7 returns 0.04999, rounds to 0.05 proc years_continuous_compounding { amount principal interest } { expr { (log ( ($amount*1.) /$principal )) / ($interest * log (exp(1.) ) ) }} # Usage years_continuous_compounding 7095.33 5000. 0.05 returns 6.999, rounds to 7 years ====== ---- ***Draft Wikipedia article on One Liners Programs , TCL Tool Control Language*** ---- There is a gold mine of One Liners Programs and content in the Tool Control language TCL 8.6 core distribution, TCL manual pages, and TCLLIB library that can be adapted or recast into brief one liners programs. These one liners programs or procedures can be pasted into the TCL 8.6 console window for quick results, reference the TCL Wiki. Some one liners programs use the return statement, return $value, or return 1 to return the results to the program line. Although many TCL programmers just rely on the last computation being returned by the one liner procedure in the TCL console window. There is some room in the Wiki publications for programming style differences. But it is usually best to put usage, credits, or TCL documentation references for the one liners procedures on separate comment lines. The random procedures make use of the random function and do not return the same answer every time. Dependence on math operator notation, helper procedures, math check examples, and special library functions should be noted in the comment lines. ---- There are pros and cons to one liner programs in TCL. One may contrast the approach to one liners programs in problem solving versus the traditional procedural approach. There are better routines and methods in faster language constructs in the current TCL core distribution and TCLLIB. Working with recursion, primes, text search, and timing the procedures will quickly show the warts on the one liners programs. To gain speed and shorter computation times, one will generally have to access the TCL core distribution and TCLLIB. Since the TCL interpreter collapses the carriage returns, skips, blank lines, and dead space of traditional written procedures into a single line of machine code, is not every script a one liner program to the parser? As grandfather remarked, the gourmet omelet, beef mulligan stew, and farm buttermilk all go to the same place. ---- ***CREDITS ON ONE LINERS*** ====== WIKI BOOKS, Programming_Examples pdf WIKI BOOKS, Tcl_Programming_Introduction pdf license https://creativecommons.org/licenses/by-sa/3.0/legalcode creativecommons.org/licenses/by-sa/3.0/ en.wikibooks.org/wiki/Tcl_Programming_Introduction Sample Math Programs, item 2, RS TCLLIB math::mean is quicker by a third over some homebrew code.

So small basic interpreter... Who used small basic interpreters? ---- A. ## The original tiny basic was distributed in assembler code for the Altair and the 8080 circuit board. Essentially, tiny_basic is a historic legacy of mankind. The original Altair BASIC was about 150 dollars each. Some USA programmers in the 1970s gave away tiny_basic free to break the monopoly. tiny_basic was the first freeware or free software package widely given to the masses (circa 1970). In Russian terms, tiny_basic is the Battleship_Potemkin of computer geeks. ---- $$$$ The analogy of using tiny_basic to control the large TCL language is like sticking an Apple computer for the human operator in front of a Cray computer. The human mind probably can only understand and use a limited set of instructions, an interface in hardware or TCL? language as a limited set of instructions might be useful. After all, the human mind was designed to chase rabbits. ---- $$ mostly as a retiree, i am trying to freshen up tcl content on the tcl wiki, adding screenshoots and what meager code i can gin up.

What is parameter or function D, not obvious from text. I have programmed the Titius_Bode equation into a Tool Control language TCL program and very interested in programming the Cerda calculations also. Quote: In Tratado de Astronomía, Cerdà obtaines (sp) the planetary distances from the orbital periods by applying Kepler's third law, with an accuracy of 10−3 . Maybe there is a contact interested in working on this item?
