To my mind an assembler without macros and conditionals is *not usable* for serious programming. Agreed, you can use it with a generic preprocessor, but the discussion then becomes how easy the pair can be used (within, say, an IDE). Comparing programming in C to a non-macro assembler for example, as appears to be a popular pastime, is hardly meaningful. Of course, C is, as has been often mentioned, itself BASICally a macro pre-processor. ;-) -- Cheers, Paul B.
