Re: Checking for existence of members and programs?

Further, possibly obvious, thought: overflow. What will happen if the 
highest xxxxx is 99999?

If you are not wedded to numbers for xxxxx, I have a fast routine to 
increment an alpha-numeric string by 1. You'd still face overflow 
issues, but it would likely take longer.
