Rd-Gl I Format - Roland DXY-1300 Command Reference Manual

3.1.2 RD-GL I Format

T he RD-GL I command format comprises the following four elements:
Command
Omission permitted
©Command
This instructs the plotter what sort of operation and setting to perform. It uses two upper
or lower case characters. In the example of Fig. 3-1,it instructs the plotter to move the
pen to the coordinate specified by the parameter that follows the command.
Papameter
This consists of coordinate values, characters and the like which are needed by com­
mands. In the example of Fig. 3-1, the command to move to coordinate 5000,5000 uses
parameters to designate the coordinate values.
There are three kinds of command: ( 1) a command without a parameter, (2) a command
that requires a parameter and (3) a command with a parameter which can be omitted.
The parameter's meaning and range vary depending on the command. The + sign of a
numerical value parameter, such as a coordinate value, may be omitted. For commands
whose parameter may be omitted, the default value of the parameter will be set if it is
omitted.
Delimiter
This is a divider between command and parameter or parameter and parameter.
Either a space " " or a " , "
The delimiter between a command and a parameter may be omitted, but that between
parameter and parameter cannot be omitted. It does not matter how many delimiters are
used or where.
