Re^5: Comparision Utility PERL

In Re^3: Comparision Utility PERL I recommended looking in the Tutorials section. If you had done that you might have found Parsing your script's command line which explains all.

my $file1=$ARGV[0];
my $file2=$ARGV1;
my $file3=$ARGV2;
my @cols = (0, 2);
so instead of 0 and 2 i want it to be user defined so how do i declare it with this method instead of Getopt::Long and other such steps

[hippo]

For those 4 variables I would do this:

my ($file1, $file2, $file3, @cols) = @ARGV;

But I would not use $file1, $file2, $file3 as names in the first place as they aren't all that descriptive. Perhaps $patternfile, $inputfile, $outputfile might be my choices.

What do you have against Getopt::Long?
