The POPD procedure changes the current working directory to the directory saved on the top of the directory stack maintained by the PUSHD and POPD procedures. This top entry is then removed from the stack.

Attempting to pop a directory when the stack is empty causes a warning message to be printed. The current directory is not changed in this case. The common block DIR_STACK is used to store the directory stack.

This routine is written in the IDL language. Its source code can be found in the file popd.pro in the lib subdirectory of the IDL distribution.
