Sequential number file

The Subroutines process of Format Control creates a Sequential Number File record when the application getnumb.fc is called. The parameters passed to the application from within Subroutines define the values in the number file fields. These values determine how the sequential number opens and what other information it contains. You can define number file values either directly in the number file or via parameters passed from Format Control. However, if you use the number file to change values also defined in the Format Control subroutines process, they are overridden by the Format Control values.
