17-6 An Introduction to HP-GL/2 Vector Graphics EN
As shown in the tables above, each HP-GL/2 command is a two-letter
mnemonic code designed to remind you of its function. For example,
IN is the Initialize command, SP is the Select Pen command, and CI
is the Circle command. Parameters are used with certain HP-GL/2
commands to tell the printer to complete the command in a particular
way.
Understanding HP-GL/2 Syntax
HP-GL/2 commands have four components: a mnemonic,
parameter(s), separator(s), and a terminator. Refer to the following
