CLARIFICATION

A reader asked about parentheticals being upper or lowercase (they should always be lowercase), but he was really asking about character continueds:

JIM (CONT'D)
Yo.

For some reason people are no longer using character continueds so much. I find them useful to remind the reader that the same person is still talking. But I'm enough of a Hollywood animal that if people are no longer using them, I'm no longer going to use them, too.

If used, they should be uppercase.
