Operating Information
Model 8756A
PEN COMMANDS PD AND PU
The Pen Down Command PD turns the CRT beam ON; the Pen Up
Command PU command turns the CRT beam OFF. Both do not move
the beam to a new location.
Syntax:
PU [term]
PD [term]
Neither command requires nor permits any parameters; both
require the terminator [term]. The beam will always retain the
beam state (on or off) of the last received Pen Command.
LETTERING
LABEL COMMAND LB
The Label Command LB allows lettering of text, experssions, or
string variables on the CRT display.
Syntax:
LB character string [ETX]
The Label mode can be terminated only by sending the ASCII
character ETX (the byte value = 0000 0011 or decimal 3) at the
end of the character string.
Before using the Label Command, the beam should be moved to the
location where labeling is to begin by using the PU command
followed by the PA command. This point will be the lower left
corner of the first character. After lettering a character,
the beam stops at the lower left corner of the next character
space.
ABSOLUTE DIRECTION COMMAND DI
The Absolute Direction Command DI specifies the direction in
which characters are lettered.
Syntax:
DI run, rise [term]
3-36
run, rise allowable values are:
1, 0 for 0 degrees
0, 1 for 90 degrees
-1, 0 for 180 degrees
0,-1 for 270 degrees
