gold Here is an eTCL script on to estimate the Drake equation. For the push buttons, the recommended procedure is push testcase and fill frame, change entries , push solve, and then push report. Report allows copy and paste from console.
In planning any software, there is a need to develop testcases.
quantity | number | units |
---|---|---|
star formation | 10. | rate per year |
stars with planets | .5 | stars |
potential life | 2. | |
actual life | 1. | |
fraction develop civilization | .01 | none |
fraction technology | .01 | none |
years available | 10000. | years |
number of civilizations equal 10.* .5 * 2. * 1. * .01 * .01 * 10000. | ||
answer: 10. | civilizations |

"Drake Equation Calculator "
Please place any comments here, Thanks. What is your purpose in binding the motion event on your main window to execute the wm title command. I.e., this line:
bind . <Motion> {wm title . "Drake Equation Calculator "}
The result of that binding is that every time you move the mouse, the "wm title" subcommand is called repeatedly. To set the window title, you just need to call "wm title . title" once, not on every event update upon mouse pointer motion.
Also, why do you define the procs pi, interlinear, pol, errorx, and height5 when you do not appear to use them anywhere in the code presented? In examples, having extra bits defined that are not used adds noise that a reader has to expend effort upon only to later learn that he/she could have ignored that part. Keeping the example focused upon only that which is needed for just the example, and nothing more, makes for a more informative, and educational, example.
gold changes: pulled procs pi,interlinear,pol,errorx,height5. and changed to wm . "title". Former idea was that user could use interpolate routine in the punched console. Conjecture below was that in a namespace version, subroutines would be available, but not all called from the namespace.
In that case, you might consider placing them into a namespace (i.e. ::gold::) and placing that common code on your main "gold" page. Then each other example page can refer to that one common location for the common items. Of course you would want to modify the examples to both load the ::gold definitions file from the gold page, and to make use of the procs therein instead of defining each individually.
