hdb,
Defensive programming aside, I believe that this may not completely satisfy the requirements. Perlseeker_1 wasn't clear if value should be printed once for each time it appeared in the files, if it could appear more than once, etc. I could see it being one of at least 3 choices: Assuming option 3, short-circuiting would speed things up assuming the real world case wasn't also the worst case.

Cheers - L~R
