Parameter Setting commands are a class of RUNOFF commands which
directly affect certain command parameters and command modes.
Right Margin, Left Margin, and Tabstops are but a few of this
class of command. The novice user to RUNOFF need not become too
familiar with this section until a firm understanding of
each of these parameters is attained.
