Note Because SP is not allowed in polygon mode, if you select a pen within
PE while in polygon mode, the Select Pen command is ignored.
z Value — Specifies data according to the preceding flag. For
example, a value following a select-pen flag should be a pen
number. Flag values are encoded in the same manner as
coordinate data. Instructions for encoding flag values follow
the parameter descriptions.
z Pen Number — Specifies the pen to be selected (black [1] or
white [0]). The pen number must be encoded into a base 64
or base 32 equivalent.
z Number of Fractional Binary Bits — Specifies the number of
fractional binary bits contained in the coordinate data. The
number of fractional binary bits must be encoded into a base 64
or base 32 equivalent (see the explanation on the next page).
z X,Y Coordinates — Specifies a coordinate pair encoded into a
base 64 (default) or a base 32 equivalent. Use base 64 if your
system can send 8 bits of data without parity. Use 7-bit mode and
base 32 coordinate values if your system requires a parity bit.
z When you are in symbol mode (refer to the SM command in
Chapter 22, The Line and Fill Attributes Group), PE draws the
specified symbol at each X,Y coordinate. When you are in
polygon mode (refer to the PM command in Chapter 21, The
Polygon Group), the X,Y coordinates enter the polygon buffer;
they are used when the polygon is edged or filled.

to 2

- 1 plotter units. If the current pen
position goes out of this range, the printer ignores plotting commands until it
receives an absolute PA or PE coordinate within the extended ranges.
pen number integer 0 to 1
number of fractional binary bits integer -26 to 26
