P e c
PE,flug [~’alueor coor(iinate pair ...,~lag]value or coordinate pair:
With this command, there should be no separators between parameters, and
the command terminator <;> must be used.
The meanings of and relation between parameters are as given in the
following table:
Flag (hex ASCII) Meaning
Next parameter
3A or BA :
Select pen
pen number, encoded as base 64 or 32
3C or BC <
Pen up
coordinates of point to move to,
encoded as base 64 or 32
3E or BE >
Fraction
number of fraction bits contained in
coordinate, encoded as base 64 or 32
3D or BD = Start PA
coordinates
37 or B7 7 Start base 32
encoding
Pen number specifies the pen to be used: Oor I (see SP)
Number of fraction bits: from -26 to +26
When there are no parameters, this command ‘updates’ the carriage-return
point.
When there are parameters, it draws lines by sending a shorter string of data
than other commands, since all parameters other than flags are encoded. In
the polygon mode, the coordinates are stored in the polygon buffer.
The encoding uses base 64 if not otherwise specified by flag =7.

PR [d.rl, d?l, dx2, dv2, .... d.w, dvn ;]
This command establishes relative plotting and moves the pen to specified
