in reply to How to Split on specific occurrence of a comma

Keep the split simple and use splice to slice up the entries into appropriate size chunks:

#!/usr/bin/env perl use strict; use Data::Dumper; my $line; my @teams; my @pending; while ( $line = <DATA> ) { next if $line =~ /^#/ || $line =~ /^\s*$/; chomp $line; $line =~ s/^[^=]*\=//; push @pending, split /,/, $line; push @teams, [splice @pending, 0, 3] while @pending >= 3; } push @teams, \@pending if @pending; print Dumper \@teams; __DATA__ Teams=PATRIOTS,BILLS,DOLPHINS,JETS,COWBOYS,GIANTS,EAGLES,REDSKINS,BENG +ALS,OILERS Teams=STEELERS,BROWNS,SEAHAWKS,RAMS,49ERS,RAIDERS

Prints:

$VAR1 = [ [ 'PATRIOTS', 'BILLS', 'DOLPHINS' ], [ 'JETS', 'COWBOYS', 'GIANTS' ], [ 'EAGLES', 'REDSKINS', 'BENGALS' ], [ 'OILERS', 'STEELERS', 'BROWNS' ], [ 'SEAHAWKS', 'RAMS', '49ERS' ], [ 'RAIDERS' ] ];
Optimising for fewest key strokes only makes sense transmitting to Pluto or beyond
