Printer, Plotter, and Spooler Subsystem Programming
%vxy or %v[...] Similar to %fxy and %f[ . . . ], but used only in the command string for
the pioout command, the Device Driver Interface Program, to generate
flags and arguments for override values specified by the piobe
command, the Print Job Manager. Flags are not generated when their
arguments are equal to predefined default values.
With %v, the values referenced by y or [ . . . ] have attribute names
whose first character is @ (at sign) and whose second character is y or
a character in the string [ . . . ].
%Ux
or %U[ . . . ]
Indicates to the piobe command that the x flag (or each flag in the
string [ . . .]) is actually referenced even though it is not referenced by a
pipeline; for example, the x flag may be referenced by a printer
command instead of by a filter in a pipeline. This prevents the piobe
command from rejecting the flag when specified on the command line.
