Error with: Using [str retain]?


#1

Hello everyone,

Big Nerd Ranch, thanks for the great book.

I have the following error when I implement the [str retain] command on page 68:

Error: "Use of undeclared identifier ‘retain’!

Can someone help me with this?

Thanks in advance,

Paul

Beginners mistake:

I used [str = retain] in stead of [str retain].

It’s working now.

Greetings,

Paul
