CLEAR GETS

CLEAR GETS

Release Get objects from the current GetList array

Syntax

       CLEAR GETS

Description

CLEAR GETS explicitly releases all Get objects in the current and visible GetList array, and terminates the calling READ, releasing any remaining objects in the calling READ, if executed within a SET KEY procedure or a user-defined function invoked by a VALID clause. CLEAR GETS releases Get objects by assigning an empty array to the variable GetList. GetList is the name of the variable used to hold an array of Get objects for subsequent READ commands. There are two other mechanisms that automatically release Get objects: CLEAR specified without the SCREEN clause, and READ specified without the SAVE clause.

CLEAR GETS has two basic uses. First, it can be used to terminate a READ from a SET KEY procedure or VALID user-defined function. Second, it can be used to delete Get objects from the GetList array when you have not executed a READ or you have saved the Get objects by using READ SAVE.
