in the program on the calculator 'test' is left .

Does that mean that
@this is a comment until the end of the line
while
@this is a comment until the next at@ while this are program statements
is until the second '@' ?

Does anyone know the proper behavior of how '@' is interpreted in all cases?

I only know that it starts ignoring at the first @, and stops ignoring after the next @, hence one reason why it's difficult to embed email addresses in a comment. This doesn't hold true for @ inside " or ' though, otherwise we'd be in all sorts of bother.

Others will be able to perhaps quote chapter/verse of applicable manuals.
