In your
first link the best suggestion was
from
chromatic. Instead of thinking in terms of executing
an external script, think in terms of calling a function.
Both are methods of executing arbitrary code, but the
advantage of a function is that it also has notions of how
to pass arguments.
The alternative is to use global variables to do your
communication. Global variables to communicate between
a mass of scripts that call each other haphazardly is a
short road to insanity. While it is the answer that you
asked for, I strongly recommend not doing that. Write
a module if you want your files to actually do something.
You may not have written a module before. If you
haven't, it isn't as hard
as people make it look. Take a look at Re (tilly) 1: Best way to fix a broken but functional program? for
a random instance. Just save that template to a file whose
name ends in ".pm", write a test script that uses it,
then start adding, running, and testing. That template
should serve you pretty well.
