Hi all.
I'm NOT using Common Lisp, but a software wich must to be customized
by using a kind-of-Lisp: CoCreate SolidDesigner.
What I'm trying to do is comparing a String and a Symbol.
My String is: "John"
And my Symbol is: John
But always I test:
(string= Name1 Name2)... it's always NIL
And then my idea is removing quotes " " from Name1, or adding them to
Name2...
I do not know what to do...

That explains a lot of the mis-communication. We are in presence of
an instance of Greenspun's Tenth Rule. :)
I do not think that many people on this group are familiar with the
"Lisp" implemented by the tool you are using. The answer that I gave
and saw were all relating to Common Lisp.
Cheers

Symbols are upcased by default by the Lisp reader (its parser).
If you do:
(string= "John" 'John)
you are really executing
(STRING= "John" 'JOHN)
STRING= is a case-sensitive comparison. Use STRING-EQUAL or put
||'s around the symbol John to retain its case.
(string= "John" '|John|)

You can try the two approaches:
(string= (symbol-name 'John) "JOHN")
or
(eql 'John (intern "JOHN"))
Note that I put the string in upper case. Common Lisp in default
reader mode will translate symbol names to upper. You might have to
experiment to see whether your Lisp implementation does the same.

This information is crucial to get help. "Lisp" is not one language, but
the one people have a right to assume in the absence of antyhing else you
mean is Common Lisp. If you do know about the default, it is not an
error to overspecify.
| What I'm trying to do is comparing a String and a Symbol.
In Common Lisp, this works because a symbol is a string designator.
I.e., when you use a symbol in a string "context", what you get is really
(symbol-name symbol). This may not be true for other Lisp, so you may
have to make that function call explicitly.

I hope you have made one of those changes at a time.
