The emulator libraries included with the languages do not support all
coprocessor instructions. The following error message results from
unsupported coprocessor instructions:

   run-time error M6107: MATH
   - floating-point error: unemulated

The following is a list of unemulated coprocessor instructions:

   FBLD   -  (emulated in XENIX 386 but not MS-DOS, OS/2)
   FBSTP  -  (emulated in XENIX 386 but not MS-DOS, OS/2)
   FCOS
   FDECSTP
   FINCSTP
   FINIT  -  (emulated in XENIX 386 but not MS-DOS, OS/2)
   FLDENV -  (emulated in XENIX 386 but not MS-DOS, OS/2)
   FNOP   -  (emulated in XENIX 386 but not MS-DOS, OS/2)
   FPREM1
   FRSTOR
   FSAVE
   FSETPM
   FSIN
   FSINCOS
   FSTENV -  (emulated in XENIX 386 but not MS-DOS, OS/2)
   FUCOM
   FUCOMP
   FUCOMPP
   FXTRACT

Also, some of the No-Wait forms of instructions are not emulated (e.g.
FNSTENV, FNINIT).
