in reply to My 'perldar' tells me there is a 'better' solution for this list operation

Hi OfficeLinebacker,

In order to reduce the 'noise factor' of your array definitions, you could also construct each as follows:

#!/usr/bin/perl use warnings; use strict; my ( @l1, @l2 ); @l1 = qw(Date IndexID Maturity OnTheRun CompositePrice CompositeSpread ModelPrice ModelSpread Depth Heat); @l2 = qw(OnTheRun CompositePrice CompositeSpread Depth); # More code here...

By declaring your variables, arrays, hashes, etc. at an earlier stage in the program, it reduces, in my experience, a portion of the frustration inherently present in the debugging process.

Hope this helps,
