Use SETQ and SET with a LIST.

[gerardo2m]

Hi.

 

I need to assign the name to a variable, but taking the name of an element from a LIST.

 

Example:

Command: (setq TEMPORAL '*Blocks*)

*BLOCKS*

 

Command: (set TEMPORAL 250)

250

 

Command: !TEMPORAL

*BLOCKS*

 

Command: !*blocks*

250

 

 

Until here Ok.

 

 

Now it is required that the name of the variable is taken from an element in a LIST:

 

(setq x1 (list "*blocks*" "*layers"))

("*blocks*" "*layers")

 

Command: (set TEMPORAL (nth 0 x1))

"*blocks*"

 

I do not require the value "*blocks*" to be assigned to the TEMPORAL symbol, but symbol *BLOCKS* is assigned.

 

 

How can this be done?

 

 

Regards.

Either:

(setq x1 '(*blocks* *layers*))
(setq TEMPORAL (car x1))
(set TEMPORAL 250)

Or:

(setq x1 (list '*blocks* '*layers*))
(setq TEMPORAL (car x1))
(set TEMPORAL 250)

Or:

(setq x1 (list "*blocks*" "*layers*"))
(setq TEMPORAL (read (car x1)))
(set TEMPORAL 250)

Looks like a homework assignment to me.

I aprecciate you support Lee, thanks.

 

It isn't homework, I was stuck with that part of the code to use MAPCAR and LAMBDA for extract info of drawing's Colecctions.
