SAVE GETS
Class
Screen Forms
Purpose
Save status of current GETS
Syntax
SAVE GETS [TO <memvar>]
See Also
@...GET, CLEAR GETS, RESTORE GETS, RESTORE SCREEN, SAVE SCREEN, FMT()
Description
The SAVE GETS command lets you save a description of the GETS in the current screen form for subsequent retrieval by the RESTORE GETS command. Since the Recital/4GL allows @...GET commands to be specified within a validation routine, the SAVE GETS command is particularly useful in letting you execute a screen form in a procedure invoked by the @...GET...VALIDATE command. When the validation procedure is terminated, the READ in the calling screen form is reactivated. This process is called nesting reads.
TO <memvar>
The optional TO <memvar> clause can be used to save the active GETS to a memory variable. This allows for multiple SAVE and RESTORE GETS.
Example
// Set up validation procedure procedure checkit parameters check save screen // Specify SAVE GETS and CLEAR GETS before @...gets save gets clear gets @1,1 get t1 // Activate gets in validation procedure read // Reactivate reads in main screen form restore gets restore screen return @1,1 get field1 @2,1 get field2 when field1="g" @3,1 get field3 validate with checkit read
