Simplify UNC usage in command line batch files

Many times a UNC path does not work properly in a command line bat file. This is a hold over from DOS, a compromise to ensure backward compatibility.

I have found a little known command (At least to me). Actually there are two of them.
PUSHD, and POPD
Call PUSHD with a UNC share as a single argument and it automatically maps the UNC share to a drive letter. (It starts at Z: and moves backward). So, if we wanted to run a few command line programs within our share we would call it like this:
pushd \\server\sharecommand1.exe command2.exe

When you are finished, and want to remove the mapping you call popd. Putting it all together we have this:
pushd \\server\sharecommand1.exe command2.exepopd

I have tested this with Windows NT 4 SP6, and it works all the way through Vista…so you are safe using it on any of these versions of Windows.
