in reply to Assigning to a hash

Assuming $columns[0] is a user name , this should work fine. I would imagine, that either $columns[0] is not populated correctly, or something more siniter is afoot ... something like a \r or \n on the username. I think adding a print above this so you can check $columns[0] would be a good idea. Also, if you show some more code, we might be able to help more.

    The perl debugger shows $columns[0] as 'willa', so I don't think any special chars are lurking...

      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;

      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

      Weird. If $columns[0] is defined correctly, you'd think that would work. Maybe posting more code would help.

      There's more than one way to screw it up...
