EXPI-ANA-"UNIf no parameters are specified, a CP command per­
forms a carriage return and line feed, moving one character-space-field
height down and returning to the margin defined by the carriage­
return point. The carriage-return point is the last point moved to using
either a PA, PR, PU, or PD command or front panel controls, or the pen
position at the last D1or DR command. Refer to The Label Instruction
in this chapter.
When parameters are specified, the CP command moves the pen the
specified number of character—space-fieldwidths to the right (a positive
value) or the left (a negative value). Note that right, left, up, and down
are relative to the label direction, where a positive value means from P1
toward P2. This is shown below.

The pen's position (raised or lowered) does not change when a CP com­
mand is executed. The parameters must be 2 -128 and < +128.
However, since there are approximately 90 character-space-field widths
and 40 character-space—fieldheights on the plotting surface, assuming
default sizing, the effective parameter range that will keep the labels on
the medium is considerably less, depending on the pen position at the
given time.
The use of the CP command to produce lettering along a line, but not
on top of it and alignment with a left—hand margin is illustrated in the
following program. The CP command in the second line moves the
label slightly above the line. The CP command in the third line moves
the label slightly below the line and the CP command in the last line
performs a carriage return, line feed to the margin established by the
