Previous, VIRTUAL
The Previous method gets the previous VIEW element, subject to the applied sort order, range limit, and filter, and returns a value indicating its success or failure.
Implementation:
If Previous succeeds, it returns Level:Benign (declared in ABERROR.INC). If it fails, it returns Level:Notify or Level:Fatal depending on the error encountered. See Error Class for more information on severity levels.
The Previous method uses the ValidateRecord method to validate records that are not filtered out.
Return Data Type: BYTE
Example:
CASE MyView.Previous() !try to get the previous record
OF Level:Benign !& check for success
!process the record
OF Level:Notify !& check for failure
!write error log
OF Level:Fatal !& check for fatality
POST(Event:CloseWindow)
BREAK
END
