Does someone have an idea how to convert a string object to a symbol?
One purpose would be some kind of variable substitution :
(setq y "z")
(setq x "y")
(print ..? x ....) -> "z"
Thanks in advance.

Have you looked at (intern "foo") or (make-symbol "foo") ? Do they
do what you want?

`intern' or `intern-soft'.

make-symbol (?)
(setq a (make-symbol "eins"))
a => eins

No, that is entirely useless since it creates a new symbol that has only
the print name "eins" but is not accessible via its name.
He wants something like
(print (symbol-value (intern x)))

Don't work for me.
Even not with
(print (symbol-value (intern "x")))
So it works:
(setq a (intern "x"))
(print (symbol-value 'a))
Probably you can explain the reasons.

Works perfectly for me.
(setq y "z")
(setq x "y")
(print (symbol-value (intern x))) -> "z"
> Even not with

That yields "y". Obviously.

Looks like you should reread what you were replying to. What I posted
works _exactly_ like the poster wanted it to work. You are doing
something completely different. Which also works in that it does
something. Just not what was required.
