CHAPTER 2
DXY-GL
2.1 Summary of DXY-GL
DXY-GL commands are mutually independent and rarely influence one another, thus making it
easy to do plotting. There are 22 commands.
They can also be used by calling the RD-GL I command.
•The following examples employ the BASIC language. Make any necessary modifications for
your particular hardware or version of BASIC.
•Ail character codes (ASCII codes) use decimal notation.
CHR$(character code) designates a character code.
• [ESC]CHR$(27) or [ESC] designates a control character.
2.1.1 Format of DXY-GL Commands
The DXY-GL command format comprises the following four elements:
Command
Delimiter
Parameter
Terminator
Omission not permitted
Fig. 2-1
Command
This instructs the plotter what sort of operation and setting to perform. It uses a single up
per or lower case character. In the example of Fig. 2-1, it instructs the plotter to draw a
straight line from the current pen position to the coordinate that is specified in the
parameters that follow the command.
Parameter
This consists of coordinate values, characters and the like which are needed by com
mands. In the example of Fig. 2-1, the command to draw a straight line up to coordinate
500,500 uses parameters to designate the coordinate values.
