Using LCDS Print Description Language

The VFU (vertical format unit) commands in the JSL illustration
shown in table 1-7 are examples of commands with identifiers.
(In this JSL, the VFU command identifiers are called “VFU1” and
“VFU9.”)
The types of commands described in the following sections are
usually coded first at the system level (following the JDL
command) because:

They require identifiers.

They typically apply to all jobs within a JSL.

These commands include:

VFU commands

TABLE commands

CRITERIA commands

PDE commands

CME commands

CODE commands

VOLUME commands

RECORD commands

BLOCK commands

NOTE: Make sure that the first command line of the JSL is the
JDL identifier command. The system level ID commands then
follow. For example:
XSML: JDL;
VFU1: VFU ASSIGN=(1,1), TOF=1, BOF=66;
“XSML” is the name of the complete JDL. The VFU command is
at the system level and has the identifier “VFU1.”
