The VCRRequest property is a reference to a variable identifying a scroll request made simultaneously with a database operation request. The WindowManager uses this property to carry out the scroll request after it complets the database operation.

For example, when the end user changes fields on a form then presses the Insert button, he simultaneously requests to save the changes and to scroll to the next record. The WindowManager completes the change request , and only then does it handle the scroll request.

Implementation: EQUATEs for the VCRRequest property are declared in \LIBSRC\ABTOOLBA.INC as follows:

     ITEMIZE,PRE(VCR)

Forward      EQUATE(Toolbar:Down)   !EQUATE(1)

Backward     EQUATE(Toolbar:Up)     !EQUATE(2), etc..

PageForward  EQUATE(Toolbar:PageDown)

PageBackward EQUATE(Toolbar:PageUp)

First        EQUATE(Toolbar:Top)

Last         EQUATE(Toolbar:Bottom)

Insert       EQUATE(Toolbar:Insert)

None         EQUATE(0)

     END
