On the 80287, 80387, and 80486, the status word can also be stored to the processor's AX register. FSTSW has wait and no-wait versions. The wait version (FSTSW) checks for unmasked numeric errors; the no-wait version (FNSTSW) does not. When the .8087 directive is used, the assembler puts the WAIT instruction before the wait version and the NOP instruction before the no-wait version. -♦-
