Do you mean TASS (does it still exist?) or HLASM. If HLASM, do 'B' and 'F' have the same semantic as in TASS, operating on the symbol reference, not on a one-digit symbol definition? The existence of multiple disparate approaches in assemblers other than HLASM is evidence of a need. There appears to be no unique best answer, but the worst answer is "none". -- gil
