FSAVE memory location

       Logic:      [memory location] . coprocessor state

     FSAVE writes the coprocessor state to the memory area specified.

     The coprocessor state includes the environment and the register
     stack; the environment includes the control word, the status word,
     the tag word, and an error block.

        Note:          After the state is saved to memory, the coprocessor
                       is initialized. See FSTENV for more information about
                       the environment.
