Roland, thanks for the tips about BLOCK IF/THEN/ELSE. I'll try it tonight and it should work. Another way I found it should work is to use GOTO and &Label. I'll have to experiment it to see which one is better.

Right now, I'm re-writing all the macros in Commander-X because of its LOGIC capability. Just thought of something, I guess I could use ActiveHome to design macros then use Commander-X to trigger the event. Things such as turning on Theater Lights could be done in ActiveHome and set a code to M1 ON for example. Then in Commander-X I only need one line, that is:
IF Time>Dusk THEN M1 ON

This will clean up the complain I had before about I have to turn of the ceiling light first then dim because Commander-X didn't have absolute dim (ActiveHome has absolute dim setting).

Well, I guess I won't abandon ActiveHome software. BTW, I'm running the Commander-X software on a 486 computer. All the programming and testings are done through a P2 though. I'm glad I can find a use of the 486.

I wish you good luck in your signal bridge project.

Simon
