PushD - Push current working directory to stack and change to new directory
Usage: pushd DIRECTORY
Works like cd but stores the current directory in a stack so it can be fetched
back later with the popd command.
Examples:
1.Workbench:> pushd ram:
1.Ram Disk:> pushd work:
1.Work:> popd
1.Ram Disk:> popd
1.Workbench:>
