TO USE XDIRJR:

Load the program by typing XDIRJR at the DOS prompt.  

To active the program, hold down the CONTROL key and at the same time press the 
period key.  A box should appear on the screen.  To see the files in the 
current directory, just press ENTER; to see the files in any other directory on 
any valid drive, type in the directory pathname and then press ENTER.  After 
viewing the directory listing, press ESCape to erase the contents of the window 
and enter another directory in the same way, or press ESCape a second time to 
erase the window itself and return the screen to its previous state.  To view a 
directory listing later, hold down the CONTROL key and the period key again; 
then proceed as outlined above.

This program is memory-resident and is designed to work from within most 
applications.
