>Guess it depends upon how you define "real" assembler.


Right, I only had one point in mind, and forgot about all the other things,
which an assembler is assumed to do :-(


What I had in mind was, that an assembler is not normally allowed to insert
instructions, modify the sequence of instructions, or the instructions
themselves. At least this was the point of some hard core assembly programmers,
which thought to know better how to write efficient code, and possibly also
wrote self modifying code.


In short, when someone says "do it exactly this way", then an assembler should
do it that way. In all other cases the assembler can provide optimizations and
address calculations, macros and other handy stuff.
