PRINT DESCRIPTION LANGUAGE (PDL)
2-12 XEROX DOCUPRINT 180 LPS PDL REFERENCE
ID level
The ID level has commands that require identifiers so that they can
be referenced by other commands in lower command levels. For
example, the ID level contains one or more VFU commands, as
shown in table 2-2. As with the other command levels any PDL
command can be specified at the ID level. The ID level must be
preceded by JDL coding, which names the JSL. For example:
XSML: JDL;
VFU1: VFU ASSIGN=(1,1),TOF=1,BOF=66;
In this example, XSML:JDL is the name of the complete JDL and the
VFU command is in the ID level.
System or JDL level
A system or JDL command set establishes installation-dependent
requirements and default values for job descriptor entries. At the
system level, JDL may be used interchangeably with SYSTEM. At
the system level, commands are specified which apply to all job
descriptor entries (JDEs) identified within a job descriptor library
(JSL). Each SYSTEM command results in the creation of a JDL when
compiled.
The SYSTEM command has the form:
jdl-name
{SYSTEM JDL;}
jdl-name
is a 1 to 6 character alphanumeric identifier specifying the
name of the JDL to be created. It must contain at least one alphabetic
character.
For example:
SAMPL: SYSTEM;
This command identifies the start of a SYSTEM command and the
beginning of a JDL. The jdl-name SAMPL corresponds to the name
of the JDL to be used when printing a job. When DFAULT is coded
for the jdl-name, the specification of a JDL parameter option in the
START command is not necessary.
Catalog level
The catalog level allows the coding of commands common to several
JDEs. A catalog can then be referenced in an INCLUDE command in
each JDE. A catalog command level is identified by the CATALOG
command and ends with the appearance of another CATALOG
command or a JOB command. CATALOG commands may contain
the same commands which appear in the JOB command.
The CATALOG command has the form:
cat-name
: CATALOG;
cat-name
is a 1 to 6 character alphanumeric identifier of which at
least one character must be alphabetic. The cat-name is referenced
by JDEs after the CATALOG command set has been defined.
For example:
POWER:CATALOG;
In this command, POWER is the catalog level identifier to be used in
the INCLUDE parameter of a JOB command.
