in thread How can I use 'split' with unknown amount of variables?

steves is right. I use split's LIMIT argument from time to time. It's quite handy.

This illustration prints each element on separate line, showing the nulls:

#!/usr/bin/perl -w use strict; my $item1 = "1,2,3,4,5"; my $item2 = "a,b,c,,"; my @split1 = split( /,/, $item1, 5); my @split2 = split( /,/, $item2, 5); # better yet, to set the size of the array at run-time... # my @split2 = split( /,/, $item2, ($#split1 + 1)); print "item1 has " . ( $#split1 + 1) ." elements:\n"; foreach(@split1){ print "'$_'\n"; } print "\nitem2 has " . ( $#split2 + 1) ." elements\n"; foreach(@split2){ print "'$_'\n"; }
