Question:
How can I make MASM take advantage of my machine's processor?
Response:
MASM allows for specification of processor type. This can be done
as follows with the first entry in the program being one of the
following types:
1. .8086 for 8086 without 8087 math coprocessor
2. .8087 for 8086 with 8087 math coprocessor
3. .186 for 186 processor
4. .286c for 286 without math coprocessor without protected
instructions
5. .286p for 286 without math coprocessor with protected
instructions
6. .287 for 286 with math coprocessor
It is important to note that it is still necessary to include an /E
or /R option when invoking MASM to enable the use of floating point
instructions.
