processes text as a comment line, allowing you to annotate
functions and programs that you create.
© can be at the beginning or anywhere in the line. Everything to the
right of ©, to the end of the line, is the comment.

on the handheld, you can enter multi-line definitions by pressing @
instead of · at the end of each line. On the computer keyboard,
