Anyone ever seen this before? The rest of the error is as follows: **** Unknown trap (TRAPS 69). ABORT: PGCMXFIX.PUB77.BETAMSS NM USER 454.00801084 U_get_unwind_table NM SYS a.0021e098 px_getsig_lowpri_$1a8 --- Interrupt Marker NM SYS a.00e0049c ?pi_call_2_handler_$8 --- Interrupt Marker The program is rewinding two datasets and sequentially reading them to perform som mass updates. The second dataset is empty (don't ask), but the code has conditions to check for this. The program is written in FORTRAN/XL on a 980/100 using 5.0. As far as I know, the program has worked before on other databases. I am running this against an old database that one of our users is using to rationlaize some of the codes we are using.
