HELP FILE ON C-- INLINE ASSEMBLY (Last modifed 16 Aug 1994)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

C-- inline assembly supports all of the 8088/8086 assembly codes, plus most
of the 80286, 80386 and 80486 enhanced instructions. All codes must start
with the $ inline assembly specifier. The list below shows all of the
assembly op codes supported by C--:
