; Subfunctions >= VDA_DE_SpecialMin, < VDA_DE_SpecialMax indicate
; private GRABBER events which VMDOSAPP just passes through to the
; GRABBER
;
; This parameter is passed through VMDOSAPP to the display specific GRABBER.
; "ranges" on the parameter allow specific info to be passed to the GRABBER
; while allowing VMDOSAPP to know about the general high level aspect of the
; event.
