This is just a guess, but it wouldn't surprise me if the rts32 process
is in stopped state due to a SIGTTIN - attempt by a background process
to read from the tty.
Try starting the job with the standard I/O file descriptors closed or
redirected, eg by wrapping the program in a ksh script like:
#! /bin/ksh
exec cobrun my-program <&- >&- 2>&-
That will close descriptors 0, 1, and 2, which will prevent the COBOL
RTS from trying to read from (or write to) the former controlling tty.
