R D - G L I

RD-GL T (Roland DG Graphic Language) is a graphic language that has been systematically

designed to operate a plotter efficiently. This language possesses 56 commands and has a high
degree of flexibility, allowing each command to be set in detail for the plotter's individual move
ment.

When using commercial software, the user does not need to understand RD-GL I , since the
software will analyze the user's drawing, choose the commands and output them to the plotter.

If you are writing you  own  program,  however,  first study the basic concepts underlying RD-GL  I
in this chapter and  then learn  the function of each command  in section  "3 .9  RD-GL I   Command
Explanation”  of  CHAPTER  3.

•The foilwing examples employ the BASIC language. Make any necessary modifications for your

particular hardware or version of BASIC.

•All  character  codes  (ASCII  codes)  use  decimal  notation.
•CHR$(character  code)  designates  a  character  code.
*[ESC]CHR$(27)  or  |ESC|  designates  a  control  character.

3.1 Summary of RD-GL I

3.1.1 RD-GL I Commands by Type of Function

There are 56 commands in RD-GL I , and they can be roughly divided into the follow seven
classifications;

(1) Initialization commands

The initial conditions and other settings.

(2) Coordinate control commands

For scaling or windows and the like.

(3) Pen control commands

Pen speed, carriage movement, drawing and the like.

(4) Enhancement drawing commands

Various drawing commands.

(5) Labelling commands

Commands that control labelling.

(6) Output commands

Commands for output of data from plotter.

(7) Digitize commands

Commands when using as digitizer.

Output and digitize commands are only effective when the connection with the computer

is a serial interface.

For an actual drawing,

a

program is created by combining the above commands. Each com

mand function is explained in section “ 3.9 RD-GL I Command Explanation” of CHAPTER
3.
