Variable reset

[kulfi]

Hi, when i am clicking first button with Key "Edit1" the value store R is 1
when i click button with key edit2 the valuse stored to W is 2
the problem here is that values are not reset like when i close the program the values should be nil for both how can i do that Please guide with any example.
thanks
(action_tile "edit1" "(setq R 1)")
(action_tile "edit2" "(setq W 2)")

(if (= R 1) (RBox))
(if (= W 2) (Box))

Kulfi,

you need to learn more about Local variables & Global variables

by default in autolisp a variable is Global and maintain it's last value
even your program is finihed unless you define it as Local variable

example

{code}

(defun some_func (x / A)

; all variables after '/' are locals in (some_func)
; defining variable as local will automaticlly set them
; to nil when the function is evaluate
; local variable scope is only inside the
; function they are defined
; they will vanish when the function is done

(setq A 2)
(setq A (+ x A))
(princ A); local A is 7
)

(setq a 5) ; define a as global
(some_func a)
(princ a) ; global a is still 5

{code}

hope this helps
Moshe

I don't know what else you have going on around this, and I haven't used (action_tile), so I'm not sure of the syntax, but I wonder: is there some reason not to just do this, and avoid the variables entirely?

(action_tile "edit1" "(RBox)")
(action_tile "edit2" "(Box)")

If there is, and also some reason you can't do it by localizing the variables as moshe-a suggests, then maybe you can solve it this way:

{code}
(if (= R 1)
(progn
(RBox)
(setq R nil)
); end progn
); end if
(if (= W 2)
(progn
(Box)
(setq W nil)
); end progn
); end if
{code}

What i want is that when i select any tile the value is 1 but this value is there even if i close the program and execute again.
what i want is that when i select the any tile the value should be one and immediatly i am out of the program the value should be 0.
thanks

Then you could change the lsp that calls and loads variables into the dcl, to load what you want.

If you want to store the last assigned values, then they must be stored somwewhere, and fetched before calling the dcl.
