Stores the current value of the DBMOD system variable


This function is used with acad-pop-dbmod to control the DBMOD system variable. You can use this function to change a drawing without changing the DBMOD system variable. The DBMOD system variable tracks changes to a drawing and triggers save-drawing queries.

This function is implemented in acapp.arx, which is loaded by default. This function pushes the current value of the DBMOD system variable onto an internal stack. To use acad-push-dbmod and acad-pop-dbmod, precede operations with acad-push-dbmod and then use acad-pop-dbmod to restore the original value of the DBMOD system variable.

Return Values

Always returns T.


The following example shows how to store the modification status of a drawing, change the status, and then restore the original status.

(setq new_line '((0 . "LINE") (100 . "AcDbEntity") (8 . "0")
			 (100 . "AcDbLine") (10 1.0 2.0 0.0) (11 2.0 1.0 0.0)
			 (210 0.0 0.0 1.0)))
(entmake new_line)			; Set DBMOD to flag 1
(command "_color" "2")		; Set DBMOD to flag 4
(command "_-vports" "_SI")	; Set DBMOD to flag 8
(command "_vpoint" "0,0,1")   ; Set DBMOD to flag 16
(acad-pop-dbmod)			; Set DBMOD to original value
