Specifying VFUs
The VFU (vertical format unit) command specifies the vertical
tabbing for the print job. There can be more than one VFU
identified. Each VFU command requires an identifier. All VFUs
are typically specified at the beginning of the system level; for
example:
Adding logical
processing
specifications
Logical processing commands are invoked when the system
locates satisfactory test criteria. These test criteria are set up for
record fields and, if met, allow special processing to take place
for such things as banner pages, record selection or deletion,
page selection from auxiliary paper trays, and page offsetting.
An example of logical processing tests and criteria is provided in
this command set:
These commands are often placed at the system level because
they require identifiers. However, depending on how many of the
jobs they apply to within the JSL, they could be coded at any of
the other levels.
