Definitely not standard 18bit macro assembler syntax.
- Has colon following labels. Macro9/15 do not.
- Uses ,I for indirect addressing. Macro9 is 'op i addr' and Macro15 is
- Allows statements with no initial tab or space, because : delimits
labels. Macro9/15 require initial tab or space if no label.
- Assumes comment after two fields or if prefaced by ". Macro9/15
require / before comment.
It's not PDP1 macro syntax either. A (lost) university software system?
