PCPI.MAC and PCPI.DOC are available from SIMTEL 20 under the directory
MICRO:(CPM-APPLE).  These files provide a method of interfacing with
Apple memory through high level languages.  So far, the interface
works as described in the .DOC files with Turbo Pascal and several C
compilers.  The only requirement is that the parameters be put on the
stack and function results returned in HL register pair.  Code can be
easily modified.
