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, macro facility, 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. You can set the default options for each of the preprocessors by using the corresponding attributes in the configuration file.
