A BASIC PDS 7.00 program gives "run-time error R6002 - Floating point
not loaded" on a machine WITHOUT a coprocessor when the BASIC run-time
library or .EXE program is created with coprocessor-only support.
Coprocessor-only support means that the BASIC run-time routines
require an 80x87 (8087, 80287, or 80387) math coprocessor to run.

The R6002 error is an initialization error that cannot be trapped in a
BASIC program.

Implementing coprocessor-only support in an .EXE program depends upon
whether you compile with or without the BC /O (stand-alone .EXE)
option, as follows:

1. If you compile WITHOUT BC /O, BASIC programs require a run-time
   module (BRT70xxx.EXE) to be present at run time. If you want to
   build a BASIC run-time module and BRT70xxx.LIB file with
   coprocessor-only support, you must invoke the BUILDRTM.EXE utility
   with the /FPi87 switch. For example:

      BUILDRTM /LR /FPi87 /DEFAULT

   (See Page 611 of "Microsoft BASIC 7.0: Language Reference" for an
   explanation of the options of the BUILDRTM.EXE utility.) You can
   then link with your new coprocessor-only run-time module, as
   follows:

      BC test;
      LINK IMPORT+test,test,,{newlibname} /NOE;

2. If you compile WITH the BC /O (stand-alone .EXE) option, you can
   directly link your BASIC .OBJ file with the 87.LIB stub file. For
   example:

      BC test /O;
      LINK test+87.LIB /NOE;
