Atomic Packing and Crystal Structure

This is the IBM version of this software package, which was
originally written for the BBC microcomputer.  This version runs
under MSİDOS or PCİDOS and is started from the DOS prompt (usually > )
by typing MENU followed by the ENTER key (which may have an angled 
arrow on your computer keyboard).  In a few seconds a menu will 
appear, from which you can make your selection of program using 
single key presses.

All the programs in the IBM version are on a single disc and there
is no need to turn over the disc to access program 4, as implied
in the booklet for the BBC version.

The disc should be inserted in the default drive (eg a:) and should be
left there while the programs are run.

It is possible to return to the main menu at any time by pressing
the ESCAPE key (usually labelled Esc).
