Re^4: Array of Arrays with Variable Names

AHA! Thanks, mreece (and others). That's what I'm looking for - and it's working now. From that suggestion, I've constructed the following snippet which is just a small portion of a much larger work:

#!/usr/local/bin/perl5 -w
use Getopt::Std;
require "/path/datafile";
getopts('f:');
chomp $opt_f ;
if ( $opt_f ) {
        @combined =  eval "$opt_f" ;
}
foreach $entry ( @combined )
{
        print "$entry \n";
}

Thanks for your patience with a beginner. I read through the warnings about variables in array names before I posted the original post, so I was expecting a lot of people to jump onto that detail... thanks for taking the time to fully understand the problem.

one last thing, which i should have mentioned in my previous post. you should check the $@ variable for errors following the eval. consider something like: `@combined = eval "$opt_f" ; if ($@) { die "could not construct a combined array from '$opt_f': $@"; }` [download]	[reply] [d/l]
