In the CB I was ineffectively trying to suggest that instead of @arrayA and @arrayB, you could more conveniently use a hash of arrays like this:
With this approach you're not stuck trying to treat diversely named variables as if they're a set (which is what you're trying to do when you deal with @arrayA and @arrayB). The hash approach holds both arrays as anonymous arrays referred to by the reference held in key A and key B. Hash key manipulation is much easier to do than contortions with variable names. The road down which you were traveling would eventually lead you to a desire to use symbolic references. The road my approach takes you down leads to proper references; much easier and safer to work with. I'd have a look at perlref, perlreftut, and perllol, and finally, perldsc for more insight. I know it's a lot of reading, but spend a couple hours with it, and you'll be miles ahead on the learning curve. Dave In reply to Re: string manipulations.
