    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)))

    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.
