Help!  I'm not much of a fortran person, so this may be
a dumb question, but I'm having problems getting something
to work in IBM's Fortran 77 for the IBM PC.  The IBM manual
says that an INTEGER*2 must be in the range of -32767 to 32767.
What happened to -32768???  The manual says that this is an
invalid integer.  Is there really no way to get 8000 hex into
a 2 byte value?  Is this something weird in IBM's implementation,
or is this standard f77?

There is no INTEGER*2 in the ANSI standard for Fortran '77.  This is a
vendor extension to the language.  Unfortunately, it sounds like they
didn't do a very good job.
