 DBF/MEMORY VARIABLES

 The DBF/Memory Variable functions provide an easy way to manage the
 memory variables usually associated with database updates using
 data entry screens.  Full screen data entry in most programs
 usually involves the same cycle of events:  declaring variables,
 initializing variables to an empty value (in the case of an add) or
 storing data to the variables (in the case of an edit), allowing
 user updates, replacing or adding the data to a database, and
 finally, releasing the variables.  The ClipOn variable functions
 allow this cycle to be stream-lined by taking care of four of the
 five steps in the cycle.  Sections of code in a program that have
 lengthy PRIVATE, STORE, REPLACE, and RELEASE statements can be
 eliminated completely and replaced with one ClipOn function.
