The Plotter Unit - Roland DXY-1300 Command Reference Manual

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 varies 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. Depending on the command, even useless parameters may sometimes require a
dummy value.
Delimiter
This is a divider between command and parameter or parameter and parameter.
Either a space or a
may be substituted for them.
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.
This manual uses the following standard formal: D500.500
Terminator
This marks the end of a command. If another command follows in succession, the ter­
minator may be omitted, but not on any other occasion [CR](CHR$(13))[LF|(CHR$(10))
is used.
In the case of BASIC, executing the command in line (1) will automatically transmit the
data row in line (2) from the Centronics port (parallel printer port).

2.1.2 The Plotter Unit

When using DXY-GL commands, the plotting unit can be selected. The plotting unit is the
actual length of 1 unit in the coordinate parameter. That is, if you wish to specify a distance
of 1mm, input 10 when 1 parameter unit is 0 . 1mm, and input 40 when 1 parameter unit is
0.025mm.
However, a parameter whose unit is expressed with " m m " or " % " will have no multiplying
effect on the plotting unit.
If RD-GL I commands have been set with the DIP switch, only 0.025mm can be selected
for the plotting unit But if the 0.1mm unit is selected with the DXY-GL command and then
executed by calling RD-GL I with the "^ " command, 0.1mm units are available for use.
may be used as a delimiter. The + or — signs of the parameter
