This page uses [Tcl]8/[Expect] 5.2 for [windows] 
to develop Slot_Calculator_Demo. 
(note: file is working in Expect5.2,
but i did not put in statement "require Expect5.2"
since lock with report error on some ports.) 
                                       
In developing a computer program or application,
it is helpful to develop analogs 
for the individual tasks of the application.

This program is finding inner diagonal of rectangular box, a subroutine was written for finding the square root of the sum of the squares for three sides, or successive numbers.
