<H2>prep - Control Value Program
</H2>
<P>
The Control Value Program consists of a set
of TrueType instructions that will be executed whenever the font
or point size or transformation matrix change and before each
glyph is interpreted. Any instruction is legal in the CVT Program
but since no glyph is associated with it, instructions intended
to move points within a particular glyph outline cannot be used
in the CVT Program. The name 'prep' is anachronistic.
