cancel/escape command in script

how do i cancel a command within a script? i thought ^c used to work, but it's not working. i'm trying to run the rtext command and then cancel out of it as a part of a startup routine i've written.

Try using (command). Exactly what command sequence do you want & where ae
you cancelling it?

 

that won't work in this case. rtext is a lisp command, so if i try to use (command) to cancel it i get an error that says, "can't re-enter autolisp". isn't there a simple way to do a "cancel" for a command in a script? the way i tried it in a .scr is:

(c:rtext)^c
regenall

i also tried it with a lisp routine:

(c:rtext)
(command)
(command "regenall")

but neither of the above are working. i want this to automatically run the rtext command and then cancel out of it when i open a drawing. we do a plot stamp with rtext on our drawing border, and it doesn't display unless after the first time you run the rtext command. i don't always remember to type in rtext before i plot and the rtext displays as a blank box on the plot.

 

Use this instead to load RText:

(if (not (member "rtext.arx" (arx))) (arxload "RText"))

That way no cancel is required.

I think you'll need to do this in a different way. AFAIK you can't send
responses to a lisp function like you can to the command function, therefore
you can't send it a cancel either. Maybe you could hack the rtext.lsp, or
figure out which of its functions causes the rtext to display and just run
that.

I still don't understand the scripting approach. If it's something you want
done on opening a drawing, I'd put it in a startup lisp. Or if it's only a
plotting issue, I'd redefine the plot command to include this step.

Sorry I can't provide any insight on the rtext display issue.

 

It used to be the backspace key would pause / cancel a script. Maybe
that has changed over the years. _David

 

hey, i tried that and it looks like it's working. thanks!

 

thanks for the help i added the lines loading the rtext function to my startup lisp routine and it looks like it's working. i was just trying the script because i couldn't get it to work with straight lisp the way i was trying to do it. of course, it didn't work in the script either!
