MBasic XOUT command with Extended code

["spudhorse" <spudhorse@xxxxxxxxx>]

Sheesh. Why are things always so hard? I'm using MBasic and have had
lights flashing all through the house for the last few days with the
XOUT command but I'm stumped when it comes to the Extended commands. I
have one lousy Leviton 6381 I need to dim and I've made gazillions of
guesses but I've come up with zip. I can turn the lights on and off
with x_on and x_off but I haven't found a way to dim the silly thing
yet.

I have a copy of the "Standard and Extended X-10 Code Formats" (XCT798)
so I have a few clues to what to put in the XOUT command but ---

For standard X-10 commands, XOUT DataPin\ZeroPin, House {{Unit},
{Modifiers} Keycode}
works just fine.

For extended commands, there's the EXTENDED keycode along with two
additional bytes (as well as the Unit).

Anyone have an idea about the format for XOUT to use an EXTENDED code?
If you're using the Basic Stamp with an EXTENDED code, that format
might help me as well.

Thanks,

Mark
