Unless... you get an NMI from something... t00b's cat is very good at that, ask him 
Ah, the Non-Maskable Scratch Interrupt? That's not just my cat though, it's pretty universal... 
DI
HALT
maybe
Is like death, no?
Better:
EI
HALT
Possible interrupt causes:
- Tacting: one brick from the ceiling fall in your stomach;
- Hearing: man, you know what time is it; (Brazillian expression, maybe didn't well know, maybe common in all cultures);
- Knightmare (really): the bats in world nine from the Maze of Galious... Umbrella rules...
Interrupt routine:
IN A,(99H)
AND 80H
RET Z
CALL WHAT_THE_FUCK
CALL OPEN_EYES_FIRST_TRYING
CALL MAIN_ROUTINE
And so on...
Do you mean that you do other things with your life besides MSXing?
No, seriously, I don´t have strict preferences, but I mainly code during the night too... And my girlfriend hates me then!
One word: coffee
I can do better programming on Mondays after 11h pm. It helps to have a bottle of Coke on the table. And it helps to have a good IDE (I use ConTEXT). There is not much secret. You just have to start programming. When you get stuck for more than 10 minutes, go watch some TV, read newspaper or go shopping. The solution for sure will appear.
About dreaming codes, I already dreamt of java codes. And it finished up gaving me the solution to the problem I had to fix. Unfortunately never happened again.
