Nil used in a list

Hi,

am trying to create a lisp to insert a block to redefine an existing one, then to exit from the command without actually inserting the new block. then i want to close and save the drawing. I have no idea what i am doing but here is what i have so far:- ;BEGIN SCRIPT (command "-insert" "a0=" nil)
(command "-insert" "a1=" nil)
(command "-insert" "a2=" nil)
(command "-insert" "a3=" nil)
qsave
;END SCRIPT

but when i run the script and it get to nil it totally stops the lisp file. any ideas?

 

Try using control C to instead of nil to exit the insert command.
(command "_.insert" (strcat blk (chr 61) fl2) ^c)
See if that helps.

does that same thing

 

Perhaps the script will perform better if you

(command "-insert" "a0=") (command)

?

inserting the new block. then i want to close and save the drawing. I have no idea what i am doing but here is what i have so
far:- ;BEGIN SCRIPT (command "-insert" "a0=" nil)

 

Any cancel in a script will stop the script.  Stop thinking like a



drafter and more like a programmer.  Instead of cancelling,



go ahead and insert it and then erase it.  The script will



take almost no more time.  LISP is not required for such



a simple task and just complicates things.

Ok what do you recommend, i have hundreds of drawings to do?

 

also, how do i erase it when other blocks have the same name?

 

Insert blahblah= 0,0 1 1 0



erase l



insert blahblah2= 0,0 1 1 0



....

Make that



erase (entlast)



 



Using "L" will only catch



those objects on the screen.



 



Either that or zoom and use an insertion point



that you know will be on the screen of each drawing.

Or... (if and only if a part of the block appears @ viewctr <center of
screen>)

Insert blahblah= (getvar"viewctr") 1 1 0
erase l

- Doug's method will find the block in the Database - instead of the
Display!
Use his...(it's better)... but knowing this variation will help you grasp
Why his works one way, and this another.
