OK, ECODE should work now. It's just a pseudotag that allows you to embed code in with Plain Old Text or HTML Formatted post modes. It looks exactly like the Code post mode -- which essentially means that it converts whitespace to a combination of space and entities, and wraps it in TT tags -- except that it is indented (with BLOCKQUOTE).
Yay. Also, if you need to put "<ECODE>" in your text, you can supply your own end tag:
Nifty. For those who have used ECODE or LITERAL (a deprecated synonym of ECODE) before, the rest works the same, except that beginning and trailing whitespace are now stripped, making it easier to use in Plain Old Text mode, where before you might get a lot of blank lines if you weren't careful.

Maybe we could reserve it for people who try and code in templates when they really should be using a Plugin or something.
Anyway, thanks. Entering code in my jounral was driving me nuts.
