Syntax: PUTLABEL INTEGER str

   PUTLABEL writes a label at the current location with rotation and
size specified by ANGLE and EXPAND (exactly like LABEL). The label is
oriented with respect to the current location according to the
argument INTEGER which can be 1 - 9 for:
                       right    center     left       justified
        label above      7         8         9 
              centered   4         5         6
              below      1         2         3
(cf. a vt100 keyboard)

   If EXPAND is exactly 1, and ANGLE is exactly 0, SM will attempt to
use a hardware character set. To avoid this use EXPAND 1.0001, or
preface the string with an explicit \\r (or include a {} if you are
using TeX strings).
