This page is under development. Constructive comments are welcome, but please load any constructive comments in the comments section at the bottom of the page. Please include your wiki MONIKER and date in your comment with the same courtesy that I will give you. Aside from your courtesy, your wiki MONIKER and date as a signature and minimal good faith of any internet post are the rules of this TCL-WIKI. Its very hard to reply reasonably without some background of the correspondent on his WIKI bio page. Thanks, [gold] 10Oct2020

***Preface***

[gold] Here are some TCL calculations for Parametric Equation Model Vaporware in calculator shell. This is a display mock up or vaporware program with dummy parametric calculations..

9/29/2020. Hi everyone, I should apply to at my parametric model a list of values (w_list) with cycle for. In each step the code must set 3 coefficients (k1,k2,k3)
======
set w_list [list {0.12} {0.14} {0.16} {0.18} {0.20}];
set k1_list [list {1.080} {1.101} {1.123} {1.144} {1.166}];
set k2_list [list {1.116} {1.213} {1.260} {1.309} {1.360}];
set k3_list [list {1.915} {2.157} {2.402} {2.649} {2.898}];
At the moment I put only this string:
for {set index4 0} {$index4<[llength $w_list]} {incr index4} {
set w [lindex $w_list $index4]
======

How can I continue?
----[gold] 10/01/2020. Look up model program on Timing Equivalent One Liners V2 at the bottom of the file One Liners Programs Compendium and TCL demo examples calculations, numerical analysis. I do not load braces around elements for computations, set k1_list {list 1.080 1.101 1.123 1.144 1.166 }, but there are many possible list formats, I guess. Suggest morf this parametric equation into graphical user interface gui that one could use. equation+of+rotated+ellipse from [GS] is maybe simple. But rotated-ellipse code looks fairly robust here and the display might be a step up. Not sure what your >> application<< is, but one could probably use a slot calculator 1) window for numeric entries controlling the calculation proc and the 2) graphics display windows. Data transfer in vaporware uses global variables. The slot calculators have 8 slots. The calculation proc supplies 5 parameters from dummy number calculations to the ellipsoidal parametric equations. The calculation proc uses a for loop, as you requested. Suggest check out pages or websites of [GS] and [uniquename] 10/02/2020 sic. Forwarded your query to the TCL Wiki on ASK 13 page . This TCL Wiki on ASK 13 page is easier <for me> to type and format an answer. [gold] 10/03/2020. What is your application? What system are you trying to model, bio, engr design, geometry, or physics? Check below link [uniquename]. This seems crack beyond what I have done. [gold] 10/7/2020, Individual could not be contacted and/or answer for further feedback. Loaded available contributions on new wiki page. Further wiki contributions welcomed on new page, but believe the abundant references on wiki are suitable, if applied.

*** Pushbutton Operation***
For the push buttons, 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.
For testcases in a computer session, the eTCL 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 will be cleared on the next solve button. The command { calculate; reportx } or { calculate ; reportx; clearx } can be added or changed to report automatically. Another wrinkle would be to print out the current text, delimiters, and numbers in a TCL wiki style table as
======
puts " %| testcase $testcase_number | value| units |comment |%"
puts " &| volume| $volume| cubic meters |based on length $side1 and width $side2 |&"
