I would be careful not to create confusion by inviting undue attention
to the notion of "sequential position". For example:
COMPARE AND SWAP
CS R1,R3,D2(B2) [RS-a]
within the "operand field", the first operand occupies the first
sequential position; the second operand occupies the third sequential
position, and the third operand occupies the second sequential
position.
If all you meant to imply is that the operand field as a whole
appears to the right of the opcode, well, so much is surely
correct.
