How to construct a block name in a list ?

[Tharwat]

I want to enter name of a Block and after that going to erase it by the command call as shown below .

 

(defun c:test (/ e a )
 (if (setq e (getstring "\n Enter Block name to delete :"))
    (progn
      (setq a (ssget "_x" '((0 . "INSERT")[color=red][b](cons 2 e)[/b][/color])))[b][color=red]<- The problem is here[/color][/b]
         (command "_.erase" a "")
      )
   (princ)
   )
 (princ)
 )

 

Thanks

Read this about the use of quoted statements, and see if you can come up with a solution.

tharwat, I have to ask: what is the logic behind your variable naming?

[Tharwat]

I got it worked Lee.

 

(defun c:test (/ e a )
 (if (setq e (getstring "\n Enter Block name to delete :"))
    (progn
      (setq a (ssget "_x" (list '(0 . "INSERT")(cons 2 e))))
         (command "_.erase" a "")
      )
   (princ)
   )
 (princ)
 )

 

Thanks

Nothing.

 

So I would ask , what kind of sence does it give ?

 

I would like to know your opinion.

I just don't see how "e" correlates to a block name string (Why not something like s/str/string/b/blk/block/n/name?) or how "a" correlates to your selection set (Why not ss/selectionset?). It's your routine, I was just wondering how your defined variables relate to what they are defining.

Its the brackets that confuse me...

Yeah .... that's the proper way in dealing with variable names and a good naming to return to when being in need of them .

 

But for me , I used "e" as a matter of Entity to get . and for "a" as the first action to do within "progn" list .

 

That's it .

Do not tell me it is the "insert tab" option ! !!!

Its more the alignment, try to align the closing parenthesis with the relevant expression - makes for easier reading.

Whatever tickles your pickle.

Whatever floats your boat...

I'm sure I'll come up with something else.
