PLIXOPT messages

The PLIXOPT variable is a varying-length character string that contains run-time options which you can specify at compile time. The messages that the compiler produces to diagnose errors in these options are different than the messages produced by the old compilers. In most cases, the PL/I messages now list an associated Language Environment message that you should read for more information.

A module containing a PLIXOPT declare will also now contain a compiler-generated CEEUOPT CSECT that contains the Language Environment encoding of the run-time options specified in the PLIXOPT string. For small modules, this CSECT can cause a substantial increase in the object size of the modules.
