Parameter Formats, An Introduction to HP-GL/2 Vector Graphics

Page 12 highlights

If you omit the second parameter you must also omit the third parameter, as shown below: LT6 The printer uses the most recently specified pattern length and mode. If you have not specified a length or mode since sending a Default Values (DF) or Initialize (IN) command, the printer uses the parameter's defaults. For example, if you send the following command (omitting the second parameter), the printer interprets the "1" as the second parameter: LT6,1 Parameter Formats You must give parameters in the format (type of units) required by each HP-GL/2 command. The required format is stated in the parameter table of each command's description, and is described as follows. 1 Integer-An integer from -1,073,741,823 (-230 +1) to 1,073,741,823 (230 - 1). The printer automatically rounds fractional parameters to the nearest integer within the range. Sending a number outside the parameter range may produce unexpected results. 2 Clamped Integer-An integer from -32,768 (-215) to 32,767 (215 -1). The printer automatically rounds fractional parameters to the nearest integer. Sending a number outside this range does not cause an error, but the number is "clamped" to the limits of the range. For example, when parsing a clamped integer, the printer treats all numbers above 32,767 as 32,767. Certain commands have parameters which are restricted to a smaller range. These ranges are listed in the parameter tables for each command. Sending a number outside the reduced parameter range may produce unexpected results. 3 Real-A number with an integer portion from -1,073,741,823 (-230 +1) to 1,073,741,823 (230 - 1). You are assured of at least 6 significant digits (including integer and fractional portion). You may omit the decimal point when no decimal fraction is specified. Sending a number outside the parameter range may produce unexpected results. 17-10 An Introduction to HP-GL/2 Vector Graphics EN

If you omit the second parameter you must also omit the third
parameter, as shown below:
LT6
The printer uses the most recently specified pattern length and mode.
If you have not specified a length or mode since sending a Default
Values (DF) or Initialize (IN) command, the printer uses the
parameter’s defaults.
For example, if you send the following command (omitting the second
parameter), the printer interprets the “1” as the second parameter:
LT6,1
Parameter Formats
You must give parameters in the format (type of units) required by
each HP-GL/2 command. The required format is stated in the
parameter table of each command’s description, and is described as
follows.
1
Integer
—An integer from –1,073,741,823 (–2
30
+1) to
1,073,741,823 (2
30
– 1). The printer automatically rounds
fractional parameters to the nearest integer within the range.
Sending a number outside the parameter range may produce
unexpected results.
2
Clamped Integer
—An integer from –32,768 (–2
15
) to 32,767
(2
15
–1). The printer automatically rounds fractional parameters
to the nearest integer. Sending a number outside this range does
not cause an error, but the number is “clamped” to the limits of the
range. For example, when parsing a clamped integer, the printer
treats all numbers above 32,767 as 32,767.
Certain commands have parameters which are restricted to a smaller
range. These ranges are listed in the parameter tables for each
command. Sending a number outside the reduced parameter range
may produce unexpected results.
3
Real
—A number with an integer portion from –1,073,741,823
(–2
30
+1) to 1,073,741,823 (2
30
– 1). You are assured of at least
6 significant digits (including integer and fractional portion). You
may omit the decimal point when no decimal fraction is specified.
Sending a number outside the parameter range may produce
unexpected results.
