>From the z/OS V2R2 XLC User's Guide: Compiler options that you specify on the command line or in the CPARM parameter of IBM-supplied cataloged procedures can override compiler options that are used in #pragma options. The exception is CSECT, where the #pragma csect directive takes precedence.
Despite the "can" I think they mean "do."

It seems to me that is backwards. Disclaimer! I worked with C, not C++. What you said is a discovery at least to me. I also find it ghastly backward. At least in other languages, you can setup your compile parameters globally somewhere and then override them inside your source one by one. Question - with what C / C++ compiler did you experience that weirdo setup? On what z/Os version? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
