iirc, you're doing this to a python script. Make the thing you need to change a command line argument to the script.

I'm confused. Is this the same problem that you describe here: http://icrontic.com/forum/showthread.php?t=69489?

If not, why don't you just go into the file and change the line you want to modify?

he wants to be able to change it automagically based on some calculated value.

he shouldn't be doing it this way, though. It should be a parameter/argument to the .py script, or he should rewrite the .m file so it's a function rather than a script.

Agreed.
