Ok. In Perl, the command line arguments are passed into the program as a pre-declared array, @ARGV.
So your program might have something like this:
my ($file1,$file2,$col1fromfile1, $col2fromfile2) = @ARGV;
Of course as with any user input, your program should check that the files can be opened and the 2 columns "make sense".

Write a simple program that gets 4 command line arguments and prints them. Let us know how it goes.

    It has been suggested to rename Perl 6 in order to boost its marketing potential. Which name would you prefer?
