RE: Increment an alpha field by "1"

Just want to be sure that I understand the requirement.

You want to take the TAA01 portion and add 1 to it so that the next utterance is TAA02.
And that the next utterance after TAA99 is TAB00.
Right?

If so, the numeric part is easy (but you knew that). The alpha portion could probably be done, it would seem at first blush, with some bit arithmetic, but perhaps I'm being a bit naïve here. Rolling TAZxx to TBAxx could be interesting.

Hi list:

I have a field (7/A) that has a combination of letters and numbers. How will the code look so I can go from, ie.:

Original value: MTAA010
Target value: MTZZ990

The first character (M) and the last one (0) will never change. Just positions 2-6

All recommended strategies are welcome,

TIA!
