Hello,
  I am working on HyperCard for a programming languages course and have run
  into a few questions involving the implementation of HyperCard.  I realize
  that some information may only be known inside apple and not available
  to the public.  Here goes it anyway.
  
  1) Why do certain commands generate errors when invoked from the MessageBox?
     e.g. if, repeat, etc
  2) What method of memory allocation does HyperCard use?
     e.g. Stack, heap, etc                    
  3) How are global variables stored and referenced?

				Thanks Much
