quick help w lisp

[vladthedog]

I know very little about lisps. I'm kinda playing around with something and I've run in to problems. I want to draw a line between two existing lines that is a certain length.

 

i start with:

 

 

(command "_line" "m2p"

 

It gives me the option to pick two parts on the screen (i'll choose the two existing lines) and then I'm supposed to select the second point for the line (which I want it to be "@0,-200"). How would I pause for user input after "m2p" but auto insert the above ? Thanks

(command "_line" "m2p" pause pause "@0,-200" "")

Thanks. I knew it was something simple like that. I'm trying to teach myself some basic lisp programming by looking at other lisps I am currently using... I hadn't seen any use "pause" yet.

Pause is a handy one, for a continual pause, try something like this:

 

(while (> (getvar "cmdactive") 0)(command pause))

 

Also, remember in macros, a pause is notified by \
