RE: Increment an alpha field by "1"

Do it in C - that does this kind of increment nicely, since it treats characters as 1-byte integers, sort or - Scott will probably have to correct me!! But you'd still want to separate the 2 sections, numeric and alpha, and check ranges and overflows.

Actually I'm not kidding!! ;-)

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!
