The #pragma runopts directive

If occurrences of the ISASIZE/ISAINC, STAE/SPIE, LANGUAGE, or REPORT runtime options are specified by a #pragma runopts directive in your source code, you might want to change them to the supported equivalent before recompiling to avoid a warning or informational message during compilation.

For more information on preprocessor directives, refer to z/OS XL C/C++ Language Reference.
