Description n specifies the additional character spacing
The units are either decipoints or defined by SSU (Select Size Unit, see page 8).
This function enlarges the inter character spacing. The function will typically be used with
proportional spacing to get effects like “spaced out” or right justification.
With fixed spacing, functions like SCS (Set Character Spacing, see previous page 19)
should be used.
The character size will not be changed.
