Say you have written the numbers to the file and have delimited them with | so the data in the file looks like this:

1111|2222|3333

You can then read them into your variables like so:

#!/usr/bin/perl -w use strict; # declare your variables my $varFile = "variables.txt"; my ($var1,$var2,$var3); # open the file open DATA, $varFile or die "Can't open file: $!"; while (<DATA>) { # chomp the line chomp; # split the line into values and assign them to your variables ($var1,$var2,$var3) = split /\|/; } # close the file close DATA;

The length of the code can be reduced substantially, but this gives you an idea of what's going on.
