What does ONCODE 9: ERROR mean in PL/I?
A SIGNAL ERROR statement was executed, or an unhandled condition of any kind was raised and fell through to the default ERROR handling because no more specific ON-unit was established for it.

Check ONCODE first to see what condition actually triggered this. ONCODE 9 by itself is a catch-all, not a diagnosis; the real cause is almost always a more specific condition that had no ON-unit to catch it.
