Incrementing Characters

Greetings from sunny Florida (where it has thunderstormed every day for the past five weeks).

Without using arrays (I can do that), is there a way to increment a character value?

CHAR = 'A';
CHAR += 1;

does not work, but is there something similar which would? I am adding a two-character suffix to a field which increments `AA`, `AB`, `AC` etc.

Thanks,
