Commands are:
EXIT Return to command language
CHANNEL Specifies line or lines on which a channel will stop.
Arguments are: ALL,LINES,EVERY.
FORMS-BREAK SPecifies the channel or channels which will stop on
the lines in the forms break margin.
MARK Directs MAKVFU to set any unspecified channel to stop
at all lines. This is equivalent to "CHANNEL n ALL"
for each unspecified channel.
INFORMATION Produces a brief summary of the VFU so far defined.
LINES-PER-INCH Specifies a lines per inch setting for the LP07 printer.
Arguments are: 6-LPI, 8-LPI, LEFT-ALONE.
LENGTH Specifies the physical length of the page. This value
is defaulted to 66 at start-up time but may be changed
with this command.
PAGE-SIZE Specifies the logical length of the page. This parameter
defines the number of printable lines per page and
the difference between it and the physical length
is the forms break margin.
HELP Produces this text.
