  Which is why I'm bothering you folks about it. I hope you don't mind.

  V6.

  Any hints where I'd best look? I don't really need the detailed 
picture about how ScummVM implements this in detail, just enough to 
write byte code that ScummVM will run.

  Is this the same 16 words that are used for holding byte variables? 
Or are there two separate storage spaces?

  Anybody know (off the top of their head) what files in ScummVM I'd 
have to look in to find out about this?

  Thanks in advance for any pointers. ScummVM is rather large, so any 
help will be appreciated.
