Appendix B. QMF Global Variable Tables

QMF provides many variables for use in your applications. In Version 3, QMF introduced the current naming convention for the callable interface. The corresponding command interface variable names are still valid.

The callable interface global variable names can be up to 18 characters long. Callable interface users can use either the old (eight character) names or the new (18 character) names; however, using the new names is recommended. Command interface users must use the old names.

The new naming convention is DSQcc_xxxxxxxxxxxx

cc

AP

QC

Beginning with Version 3.3, QMF provides a special procedure named Q.SYSTEM_INI that allows you to customize global variables at initialization. See the QMF Installing and Managing book for your operating system for more information.
