PL/I Multitasking ILC considerations

User-written condition handlers registered with the CEEHDLR callable service are not supported in PL/I multitasking applications.

When a Fortran enclave-terminating construct, such as a STOP statement, is executed from a Fortran routine in a PL/I subtask, the entire enclave is terminated.

See z/OS Language Environment Programming Guide for a detailed description of Language Environment condition handling. For information about Fortran condition handling semantics, see VS FORTRAN Version 2 Programming Guide for CMS and MVS.
