I  have a FORTRAN program which is supposed to test to see if there is
an 8087 present, and if so, use it.  If not, it is supposed to use the
8088  for  arithmetic.   It  is  compiled in Microsoft (IBM/Microsoft)
FORTRAN and works fine on the PC, PC Portable, and PC-XT.  In  running
it  on  the  AT,  if an 80287 is installed it works fine.  If not, all
numbers are displayed as 1.0.  Has anyone encountered this?   What  is
the  cause,  the 80286 or the software?  I understand Lifeboat C has a
similar problem.  Does  IBM  know  about  it?   Is  it  to  be  fixed?
