Using LCDS Print Description Language
VFU command
The VFU command assigns output line numbers to printer
carriage control channels. These Line to Channel assignments
perform the same function as the printer carriage control tape on
a conventional line printer.
The VFU command also assigns line numbers to the top of the
form (TOF parameter) and the bottom of the form (BOF
parameter). TOF and BOF are used for prejob page alignment
and for page overflow processing.
ac identifier
You must specify an identifier of the type
ac
(at least one alpha
character required) when defining the VFU table, and reference
it in the VFU parameter of the LINE command. The VFU
command must precede the referencing LINE command.
VFU command parameters
The following table summarizes the VFU command parameters.
The following sections describe the syntax of the command
parameters and explain the parameter options.
