Undersatandable if you don't know C. Just thought I'd throw it out there in case you did. Ad far as using different files, you're going to want to look at use and require.

There's some significat differences between the two and you're going to want to read up on them first. A basic example of require would be..

#!/usr/bin/perl -w # # This is the main script # use strict; require "test.pl"; somefunc("test");
And the required file...
#!/usr/bin/perl -w # # This is test.pl # use strict; sub somefunc { print shift, "\n"; } 1; #file needs to return true on require or use.
Now this probably isn't a good example, but it shows you the basic usage. You're probably going to be better off creating modules and useing them instead. I'm still relativly new to perl so I can't give you all the reasons, but the 2 bigest benifits of modules and use will be 1) you're not going to (or you can avoid) polluting your namespace. Which means you can do something like DaftMagic::Cast($source, $target, $spell); where "Cast" doesn't exist in your namespace. Keeps things a little cleaner. 2) Things are loaded at compile time instaed of run time.

I'm sure others could give you the pros and cons of requiring files vs. using them.. and the usage of modules. There's also some other reading - perlmod, perlmodlib, perltoot, and perlobj.

HTH..
