Universally Available Display Commands in DEFINE

There are some commands which may be used at (almost) every stage of your define session. If you build up a complicated molecular geometry, you will find the dis command useful. It will bring you to the following little submenu:

ANY COMMAND WHICH STARTS WITH THE 3 LETTERS  dis  IS A
DISPLAY COMMAND. AVAILABLE DISPLAY COMMANDS ARE :
disc  <range> : DISPLAY CARTESIAN COORDINATES
dist  <real>  : DISPLAY DISTANCE LIST
disb  <range> : DISPLAY BONDING INFORMATION
disa  <range> : DISPLAY BOND ANGLE INFORMATION
disi  <range> : DISPLAY VALUES OF INTERNAL COORDINATES
disg  <range> : GRAPHICAL DISPLAY OF MOL. GEOMETRY
<range> IS A SET OF ATOMS REFERENCED
<real>  IS AN OPTIONAL DISTANCE THRESHOLD (DEFAULT=5.0)
AS AN EXAMPLE CONSIDER  disc  1,3-6,10,11  WHICH DISPLAYS
THE CARTESIAN COORDINATES OF ATOMS 1,3,4,5,6,10,and 11 .
HIT >return< TO CONTINUE OR ENTER ANY DISPLAY COMMAND

Of course, you may enter each of these display commands directly without entering the general command dis before. The option disg needs special adaption to the computational environment, however, and will normally not be available.
