> People are prepared to argue PoPs interpretation with John Ehrman ???.
I appreciate the laudatory comment, but I'm as blunder-prone as anyone else. (And a very poor chess player.) To me, the topic we're discussing is with the word "operand". (1) In the PoP, an operand is an object being operated on by, or involved in, an instruction. (2) In an Assembler Language statement, an operand is determined by its sequential position in the "operand field" of the instruction. (3) You can also make a case for an operand being an object to which something happens at execution time. Assembler Language can be even more difficult if the intended sense isn't clear from context.
