Is there a way to determine (b

Hello,
 
Is there a way to determine (by lisp) if a command is in progress?
I want to make a macro that can do either the first thing (if a command is in progress) or or the second thing if there is no command in progress.
 
TNx.

Cmdactive maybe?

(if (> (getvar 'CmdActive) 0))   (do first);if True   (do second);if nil)
You'll probably run into problems if you try and execute functions/commands while a command is active.

YOu mean like this:
 
 

(if (> (getvar 'CmdActive) 0)   (do first);if True   (do second);if nil)
 
 
Thank you. I will try and post my reaction soon.

CMDACTIVE is actually bit-coded, so you might want to look into such functions as logand/logior.
