Summary

After you have formatted your catalog, you access it with your program. This access is done using the ''CATOPEN, CATREAD, and CATCLOSE intrinsics. The CATOPEN intrinsic is used to open the formatted catalog. CATREAD reads messages from the catalog and substitutes run-time parameters; they may be in positional or numerical form. The substitutional parameters must be strings with an ASCII null appended. CATCLOSE closes the catalog.
