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:
- .8086 for 8086 without 8087 math coprocessor
- .8087 for 8086 with 8087 math coprocessor
- .186 for 186 processor
- .286c for 286 without math coprocessor without protected instructions
- .286p for 286 without math coprocessor with protected instructions
- .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.
