Thank you for your reply Laurent_R.

That is close to what I want. Again, I probably did not do a good enough job explaining what I want. Sorry. The look up you have is close, but I want a check similar to yours that will check for the numbers between the range. Given '7-12', the code will check for 7,8,9,10,11, and 12.

Is there something I can use that is similar to your check, but will essentially look for this ?

 if ( exists $hash{7} || exists $hash{8}... exists $hash{12} )

Ideally

 if ( exists $hash{7..12} )

Thanks.
