Each procedure may have one Main map, set up using the Screen/Form Design option of the Procedure Body Editing Menu. This map determines the appearance of, and strongly influences the processing of, the fields that will be processed in the procedure body's field processing. Refer to Map Editing for a more detailed discussion of this topic.
For screen based procedures the main map is set up using the Screen Design dialog, while for procedures that print the similar Form Design dialog is used instead.
