Summary: It is hardware, CRAY doesn't divide


This problem is not a FORTRAN problem.  The CRAYs have no divide instruction,
but the compiler assumes that it does.  It takes many instructions to assure
that the quotient is "correct" in the sense that problems about sign of the
remainder do not occur.  I suggest that the AMOD code be rewritten to take
the problem into account.
