  Syntax:   FST dest

  Description:
 
     Stores the value in ST to the specified memory location or
     register. Temporary-real values in registers are converted to the
     appropriate integer, BCD, or floating-point format as they are
     stored. With FSTP, FISTP, and FBSTP, the ST register value is
     popped off the stack.
 
     Memory operands can be 32-, 64-, or 80-bit real numbers for FSTP,
     or 16-, 32-, or 64-bit integers for FISTP.
