Each image display has two independent cursors available.
In addition each cursor shape can be defined. The variety of possibilities
available for various cursor forms and types defies a simple explanation here
that would make much sense. The interested user is referred to the
command TUTORIAL/CURSOR which gives a demonstration of the possible
cursor shapes.
The cursor(s) are controlled interactively by a special device e.g.
tracker ball, joystick or mouse. Detailed information on how to operate
the cursors can be found in Appendix 
.
In general there is a switch for each cursor to define its status ON/OFF.
When a cursor is active (ON) its position can be read by pressing the
key. To exit an interactive cursor command one normally has to
switch the cursors off and press the 
key.
The commands associated with cursor control operations are:
SET/CURSOR - enable selected cursor
LOAD/CURSOR - load a programmable cursor
GET/CURSOR - read cursor positions
CLEAR/CURSOR - disable cursors
