command "undo" in Lisp

Hello .

I have seen lots of users using the undo command in different types and return values.

So what are the complete types of undo command uses in Lisp ?

Some users prefer it (command "_.undo" "group") and others

(command "_.undo" "......... and so on.

Thanks.

I'm not sure I understand you correctly... do you mean this type of useage:

;; Set an undo mark
(vla-startundomark *activeDoc*)

Edit: If so, then inside the VLIDE, hit the Apropos button, and search for "undo"

Thanks a lot .

I meant the use of UNDO command itself .

Some users use it with "end" and "group" and I would like to know the rest of using operations with UNDO command.

And actually what's the meaning of group with undo ?

Appreciated a lot.

Command: UNDO
Current settings: Auto = On, Control = All, Combine = Yes, Layer = Yes
Enter the number of operations to undo or [Auto/Control/BEgin/End/Mark/Back] <1>:

Way to go big guy! :wink:

That's all I know with the normal use of Autocad command.

I meant there are lots of other uses of undo command with Lisp I have seen before ,and what I

could remember the one which is with group right now.
