KEYBOARD GRAPHICS FUNCTIONS
Graphics functions commands in the form of escape sequences can be entered at the terminal
keyboard by the operator. In addition, certain graphics functions are performed via the set of
graphics control keys located to the right of the normal ASCII character set (see figure D-l).
Table D-l contains a list ofthe keys and a description of their functions. These keys function in
either local or remote operation. This allows a combination of operator and program control of
graphics functions. Refer to the User's Manual for detailed information on using the graphics
control keys.
Figure D-l. Location at Graphics Keys
Each key (except the two TAB keys and the decimal point key) performs one of two functions,
depending upon the current state of the keypad. Pressing.

betwe-en graphics and numerics functions. The current state of the keypad appears as
GRPH PAD
or
HUM PAD
in the status line at the bottom of the screen display (the 27th row). The
default state is NUM PAD. The current state of the keypad, however, is stored in nonvolatile
memory; if you set the keypad to GRAPH PAD and turn off the terminal, the keypad is still in
GRAPH PAD state when you reapply power. Hard reset _
