in reply to Re^5: Comparision Utility PERL
in thread Comparision Utility PERL

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

    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?

      i am very new to this hence learning it from easy way
