Do you simply want to translate all valid zones into one of two cannonical zones, or do you also want to detect invalid zones? I.e., do you want to flag zones of 0-9 as errors.

But what if I find x'A1', x'B1', or x'E1' for overpunch values? What is the shortest way (in terms of assembler instructions) to validate these into just two classes -- positive and negative?
