The global listing generator is called with the START-CPLUS-LISTING-GENERATOR command. The input source for the listing generator consists of CIF information, which is created by the compiler for each compilation unit and stored in PLAM library elements (type H), in cataloged BS2000 files or in POSIX files (see "MODIFY-CIF-PROPERTIES"). All listings generated by the global listing generator are written to a single output file, which may be the system file SYSLST, by default, or the output file specified with the OUTPUT option. The listing generator uses the CIF information stored for local cross-reference and project listings to create global (i.e. multi-module) crossreference and project listings. The remaining listings are generated per source file.
