we receive no output. When the last comment line is left out, output is as expected. Condition codes are 0 in both cases.

It is not a failure, thie version of the compiler is based on PUNCH CARDS wiith possible line numbers after col 72. Thus, the comment continues (as specified in the standard), and, in this case, the "statement" is ignored. A nice catch of "incompatibility" . TLNR: Works as designed.
