This question triggered a brain cell.
I remember a computer architecture, possibly one that was known for its beautifully symmetric instruction set, with an assortment of distinct mnemonics for different conditional branch instructions. All were of the form
JUMPxx where the xx named the condition. I don't remember the exact spelling of any but two of them
JUMPAmeant "jump always," and
- Just plain
JUMPmeant "jump never" (i.e., the assembler allowed you to write "
JUMPeffective address," but it silently ignored the address expression, and it emitted a no-op.)
What architecture am I remembering?
