WRITE LIST-LINE FROM BAD-EXIT-PGM, STOP RUN.

\If the call to retrieve exit program information is succe￿ssful,

\check to see if there are any exit programs to call.

\

\The receiver variable offers enough room for a minimum of￿ one

\exit program entry because the receiver variable was dec￿lared

\as 35ðð bytes. Therefore, this example only checks the

\number of exit programs returned field. If the receiver

\variable were not large enough to hold at least one entry￿,

\the bytes available field would need to be checked as wel￿l as

\the number of exit programs returned field. If the number of

\exit programs returned field is set to zero and the bytes￿

\available field is greater than the bytes returned field￿, the

\API had at least one exit program entry to return but was

\unable to because the receiver variable was too small.
