In the embedded world GOTO is usually much faster and clearly not a 
bad thing at all!  Weird behavior like you describe is part of the 
charm, me thinks.  It will be interesting to think in bits and shift 
rights instead of Web Services and enterprise processes for a change.

Don't think for a moment that I was criticizing your code.  I 
sincerely wasn't - just my glib self getting me into hot water again.
