.8087            Enable 8087 Instructions                      MASM Directive

.8087

Enables assembly of 8087 instructions and disables assembly of 80287
instructions.

Note:      When using .8087 or .287, include /R or /E on the MASM
command line to specify how the assembler is to handle
floating-point instructions.  They are defined below:

/R         Assembler generates actual instruction code for
floating-point instructions.

/E         Assembler generates code that can be used by a floating-
point emulation routine.

Notes:     Place all Instruction set directives at the beginning of
the source file to insure that all instructions in the
file are assembled using the same instruction set.

If no instruction set directives are specified, .8086
and .8087 are used.
