Is this data being read from a file ? a database? Knowing where it comes from may help me formulate a guess. What you have should work fine. If you do something like the following , does it work any better (not that it should) : `my $key = $columns[0]; $hash{$key} = 1;` [download] Also, you may want to use Data::Dumper to print out the data structure to find out what is getting created. `$ perl -e 'do() \|\| ! do() ;' Undefined subroutine &main::try` [download]	[reply] [d/l] [select]

Weird. If `$columns[0]` is defined correctly, you'd think that would work. Maybe posting more code would help. Also, check here for other ways to Return a Unique Array. Rich36 There's more than one way to screw it up...	[reply] [d/l]
