C:\WINDOWS>HELP PUSHD
Stores the current directory for use by the POPD command, then
changes to the specified directory.

 path        Specifies the directory to make the current directory.

network paths in addition to the normal drive letter and path.
If a network path is specified, PUSHD will create a temporary

defined drive letter.  Temporary drive letters are allocated from
