Thanks for the comments so far, my array @GrpIDs now contains: 
warn Dumper @GrpIDs:

$VAR1='123';
$VAR2='456';
...

[download]

String $query contains '123'. I'd like to know how to create a match/test so that I get a positive result for things which are in the array @GrpIDs that have an entry in the string $query.
