Re^2: Range Operator in If Statement

[Not_a_Number]

I'm SURE there is a 100 different ways to do this...

Here's one way to assign to $bundle that requires a lot less typing. Replace your call to get_bundle and the sub itself with:

$bundle = [ 'A' .. 'F' ]->[ ( $ref_number - 1 ) / 8 ];

Update: Removed unnecessary parentheses around the arrayref.
