Offhand, I don't think so. IIRC, the PUSHD and POPD x86 instructions came with 80386 (32-bit) CPUs (D stands for Doubleword, IIRC, or 32-bits - those instructions push and pop a 4-bytes register or memory location), but the pushd and popd commands came with the BSD C shell, which is much older.

Ohh. I guess it seemed much more obvious to me that the assembly instruction set would have been set down before any shell scripting commands. But that makes a lot of sense.
