You could always make an external call to perl to invoke this program.
For example, using exec or system. E.g.,
exec('perl', 'thecalledscript.pl', $filename);
It depends on just what thecalledscript.pl does and whether or not
your program needs to do anything in response. I'm unfamiliar with
best practices regarding invoking a Perl script with require, but my
intuition says that it looks like abuse. :)
I've sort of begun to think that nearly any program that you write
should be mostly implemented in a library of sorts to optimize the
software-to-software communication between programs. Then you'd just
basically interface that library with the user and standard
input/output mechanisms. If you control thecalledscript.pl then
perhaps you could consider moving the guts into a Perl module, leaving
only the necessary glue in thecalledscript.pl to interface with the
user and/or standard input/output mechanisms.
