[esp-r] Re: Perl script

[victor bunster]

Thanks Jon, now I'm more clear,

I think working with the text mode and calling the menus with their
characters should be more than enough.
But specifically, how do you call that commands with Perl (or the C shell)?
could you give me a short example?
For example, how write and run a script that draws a thermal zone and place
a goup of windows with a for loop.

I'm working in something like this:
-create one 10x10x10m zone,
-place one 1x1m window,
-simulate and read the thermal data,
-move the window 1m in a random direction
-simulate, and if better maintaind or else go back.

The idea is to automatize this algorithmic process in order to increase its
complexity later, but I'm stuck at the basics.
I'll take a look to the developers API, I'm looking for a software flexible
enough to code some small procedures combining geometric changes &
simulation/evaluation and ESP-r looks perfect.

Regards

Victor
