ssget & use of variables

[NancyM]

AutoCAD2000...ssget & variables at "10"

why does this work...
(ssget "X" '((10 20 -12 0.0)))

and this does not...
(setq pt1x 20)
(setq pt1y -12)
(ssget "X" '((10 pt1x pt1y 0.0)))

I really need to have the x & y values as variables.

Appreciate any input. Have a great Christmas!

change the second one to something like:

(ssget "X" (list (list 10 pt1x pt1y 0.0)))

You are quoting a list that contains variables that
require evaluation.

IOW:

(setq a 10 b 20 d 30)

'(a b c) -> (a b c)

(list a b c) -> (10 20 30)

Instead of quoting the list, use LIST:

(ssget "x" (list (list 10 pt1x pt1y 0.0)))

(setq pt1x 20)
(setq pt1y -12)
(ssget "X" '((10 pt1x pt1y 0.0)))

I really need to have the x & y values as variables.

It doesn't work, because you are using the QUOTE symbol which prevents the evaluation of your variables.

Use (ssget "X" (list (list 10 pt1x pt1y 0.0))) instead.
