Hi Joel,

Your example shows A-Z, 0-9.
I would use 0-9, A-Z.

I would:
- convert from base 36 to base 10
- increment by 1
- convert from base 10 to base 36

A 4 char field with base 36 will range from 0 to 1679615 in base 10.
You'll have to code something that will restart at 1 when trying to
increment past 1679615.

Yours truly,

I have a length 4 alphanum field which I need to find the next value
(incremented by one value).


A001 => A002



And my shop would like it done in COBOL, but any algorithm will suffice.

Maybe use a base 36 table???



Thanks in advance.
