<<TOC>>

[gold] Here is some eTCL starter code for 
*** Pseudocode and Equations using coefficients   ***
%|   Pseudocode with some Equations   |   |%
&|namespace path {::tcl::mathop ::tcl::mathfunc} ||&
&| pseudocode: mortar = vol of walls times 1/6 , 144. c.m.* (1/6) or 24 c.m.   | |&
&|  pseudocode: brick volume = 0.33*.33*.08, or 0.0087 cubic meters  | |&
&|  pseudocode: answer is mandays of labor or silver pieces +- error   | |&
&|      workdays on foundation  = vol of foundation / coefficient  | |&
&|         =  36 / 3  or  12  workdays  | |&
&|      workdays making bricks = number of bricks / coefficient1   | |&

***Testcases Section***

In planning any software, it is advisable to gather a number of testcases to check the results of the program. The math for the testcases can be checked by pasting statements in the TCL console. Aside from the TCL calculator display, when one presses the report button on the calculator, one will have console show access to the   capacity  functions (subroutines).

*** 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, but takes away from computer "efficiency". 

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 (which 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, but is not recommended as computer efficiency is impaired. 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   |&"
