While it appears that the OP needs to learn more about references to use multidimensional arrays, he raises a good question about iterating over multidimensional or other complex data structures. I'll just briefly put in a plug for Brad Bowman's excellent module, Data::Rmap, which offers several ways to accomplish this. In this instance:
use Data::Rmap; @days=qw(mon tues wed thurs fri sat sun); @cols=qw(red orange yellow green blue indigo violet); @vars = (\@days, \@cols); rmap {s/e/E/g} @vars; print Dumper(\@vars); -- $VAR1 = [ [ 'mon', 'tuEs', 'wEd', 'thurs', 'fri', 'sat', 'sun' ], [ 'rEd', 'orangE', 'yEllow', 'grEEn', 'bluE', 'indigo', 'violEt' ] ];
