Somtimes i have this problem both in C++ and PERL.
In PERL you could use the fact that you can redirect any print ng to screen to a file insteed.
Create a filehandle tex. $myDebug = open(....
and switch screen to this file with select
Example:
----------------------------------
#!/usr/bin/perl
use warnings;
use strict;
open (DEBUG, ">debug.txt") || die $!;
print "Before redirecting to file\n";
select DEBUG;
print "This goes to de files\n";
select STDOUT;
print "And now we back\n";
-------------------------------------
