assembly - Write the value in the 8087's top of stack to a variable in memory -

-

i installed math coprocessor in old 286 computer, , i've been playing around it's instruction set in assembly.

i own intel programmer's reference 8086 cpu, , has nice long section on programming 8087. i've learned need know section, never mentions how transfer value 8087's register stack memory variable.

there doesn't appear 8087 instructions moving data around, except popping stack , exchanging data around within register stack.

so, how transfer st(0) temporary real variable in memory.
