Replace command not working

I can't get the Replace command working.
Also the Replace method for a string doesn't seem to work.

Print Replace$("This is a test to replace spaces", Chr(34), "")

Local TestString$ = "This is a test to replace spaces"
Print TestString.Replace(Chr(34), "")

It just prints the exact same text, without replacing the space-chars with nothing ("").

The ASCII for a space is 32 not 34.

However it still does not appear to work.

Doh, I feel sooooooo stupid right now.
Just found out myself too (by looking into MSDN's ASCII table).
It works now.

Print Replace$("This is a test to replace spaces", Chr(32), "")

Local TestString$ = "This is a test to replace spaces"
Print TestString.Replace(Chr(32), "")

I just realised why it didn't work for me;
I assumed the replace method for a string actually modified the string which it does not. It simply returns the modified string.
