VCRRequest | &LONG |
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)
