ASSERT

The ASSERT option controls whether ASSERT statements call a default library routine that will raise the ASSERTION condition or a routine provided by the user.

The default is ASSERT(ENTRY).

ENTRY

Specifies that ASSERT statements will call user-provided routines with the interfaces documented in the Enterprise PL/I for z/OS Language Reference.

CONDITION

Specifies that ASSERT statements will call library routines that will raise the ASSERTION condition with an appropriate ONCODE built-in function.
