The PL/I compiler allows you to select one or more of the integrated preprocessors as required for use in your program. You can select the include preprocessor, the macro preprocessor, the SQL preprocessor, or the CICS preprocessor and the order in which you would like them to be called.
Each preprocessor supports a number of options to allow you to tailor the processing to your needs.
The three compile-time options MDECK, INSOURCE, and SYNTAX are meaningful only when you also specify the PP option. For more information about these options, see MDECK, INSOURCE, and SYNTAX.
