Returns
Category            Development
Syntax              SET KEY xxx to SCMOD
Description         SCMOD() is a tool for online building and
                    modifying of the SCROLLER.DBF used for
                    SCROLLER() lookup tables.

                    When called by a SET KEY, it recieves the
                    PROCEDURE and VARIABLE parameters from the
                    calling PROCEDURE. It then determines if there
                    exists a matching record in the SCROLLER.DBF.
                    If so, the lookup definition may be modified.
                    Otherwise, a new lookup definition may be created.

Examples found in   No examples in the library. This is a development
                    tool.

Notes               Be sure to declare SCMOD external.

Warnings            SCMOD() will blow your get stack. It is primarily
                    for development, so this should not be a problem.
                    If you have a library that saves and restores gets,
                    this would be an indicated place to use them.
