In article <9103180137.AA13890@ucbvax.Berkeley.EDU> you write: >It seems that we're trying to say some opcodes, say LA is a machine >instruction, while other more complicated and implemented in microcode >instructions are not 'instructions'. Where would you draw the line? Clearly If you can execute that opcode on any machine in the same class, independent of the operating system, and it always performs the useful defined effect, it is an instruction. If the opcode is designed to perform a special purpose procedure for a specific software environment, and makes no sense outside that environment, it is a microcode assist. The term 'same class' above is deliberately vague. -- =*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= Neil W.
