What You'llLearn in This Chapter
In this chapter you will learn about character sets and labels used to
create effective annotated graphics. You will learn how to designate
and select character sets, how to use the label instruction with both
constant and variable parameters, and how to set the size, slant, and
direction of labels. Character spacing, moving the pen any number of
character widths and/ or lines, and designing your own characters will
also be discussed.

Terms YouShould Understand
Label Terminator — the final character in every label string; it takes
the plotter out of label mode so that characters are no longer drawn but
are again interpreted as HP-GLinstructions and parameters. Its default
value is the ASCII character ETX (decimal equivalent 3), but it may be
redefined using the DT instruction.
Character Space Field — the space occupied by a single character, to­
gether with the space between it and the next character and the space
above the character which separates it from the previous text line.
*Not available with Option 008.
