Topic: get from an list only the var name

[Humbertogo]

I have a list with  variant
something like  ("HEIGHT 01" . 1410.0) ("HEIGHT 02" . 1730.0) ("HEIGHT 03" . 1830.0) ("HEIGHT 04" . 1720.0) ("HEIGHT 05" . 1400.0)

i try to get from the list only the var name

Is there any way to handle this?

Thanks

You mean you want the variable's symbol name to which this list is applied? Or are you referring to wanting something from a variant/safearray?

Sorry for my confusion, could you possibly post some sample code? Maybe then I'd be more enlightened  :-[

The list in your post looks like an association list, the usual way of using this is like so:

Code - Auto/Visual Lisp: [Select]

_$ (setq lst '(("HEIGHT 01" . 1410.0) ("HEIGHT 02" . 1730.0) ("HEIGHT 03" . 1830.0) ("HEIGHT 04" . 1720.0) ("HEIGHT 05" . 1400.0)))
(("HEIGHT 01" . 1410.0) ("HEIGHT 02" . 1730.0) ("HEIGHT 03" . 1830.0) ("HEIGHT 04" . 1720.0) ("HEIGHT 05" . 1400.0))
_$ (cdr (assoc "HEIGHT 03" lst))
1830.0

If by "var name" you're referring the to association keys, then perhaps:

Code - Auto/Visual Lisp: [Select]

_$ (mapcar 'car lst)
("HEIGHT 01" "HEIGHT 02" "HEIGHT 03" "HEIGHT 04" "HEIGHT 05")

Thanks
that is exact what  i need to do (mapcar 'car lst)
