Built-ins for condition handling

PL/I also provides condition-handling built-in functions and pseudovariables. These allow you to inspect various fields associated with the interrupt and, in certain cases, to correct the contents of fields causing the error.

These built-in functions include:

DATAFIELD
ONCHAR
ONCODE
ONCONDCOND
ONCONDID
ONCOUNT
ONFILE
ONGSOURCE
ONKEY
ONLOC
ONSOURCE
ONWCHAR
ONWSOURCE

For detailed information on these condition-handling built-in functions and pseudovariables, consult the PL/I Language Reference.
