Start Oscail and using the Select Job and Directory
button,
, navigate to \ortex
and select jh21.ins. (You can select any file of the type jh21.xxx to get
the jh21 job onto the status line. Oscail does not open any files it just points
to the jobname and directory indicated on the status line.)

Click the Check Files and unit cell button,
,
and select the default on each subsequent dialog.
The following information is in the LST file.

This file check action also provides a quick way to "sync"
INS and RES files. If one of INS or RES is present for
the current job and the other is absent, then the absent one is copied from the
one that is present. After "syncing" the INS file will be used by
ORTEX and other programs.
Click the ORTEX button,
,
to start ORTEX and select defaults.
The ORTEX picture should appear.

ORTEX starts in Line mode. In line mode structures may be edited and
the red part of the structure is towards the back. Clicking on the Atom mode
button,
, will start atom
mode.

The best way to learn how to use ORTEX is to look at some of the tutorials that
are close to what you would like to do and then try the program for yourself.
