Coding System Level Commands With Identifiers - Xerox DocuPrint 100 Software Manual

PDL principles and procedures
JDL name
Begin your JSL by deciding on a name for the compiled JDL and
entering the "JDL" command on the first line of the JSL. The
JDLNAME is a 1 to 6 character alphanumeric identifier
specifying the name of the JDL to be created.
Select a name that is related to the function of the JDL and
identifies the type of jobs you are creating. For example, if your
site has several input sources, you might want to name the JDL
for an online job "JDLONL: JDL;."
The format for naming a JDL is:
JDLNAME: JDL;
For example, you might name a JDL containing short edge feed
(large paper size) jobs:
JDLSEF: JDL;
When a JSL is coded, the word SYSTEM is sometimes used in
place of JDL. The meaning is exactly the same. In the following
example, the JDL name SAMPL corresponds to the name of the
JDL to be used when printing a job. The command can be stated
in the following ways:
SAMPL: SYSTEM;
SAMPL: JDL;
JDL or system level commands
PDL commands coded at the JDL or system level establish
default print job characteristics. Commands that are common to
all the jobs in the JSL are listed at this level so that they need not
be coded in every job in the JSL. System level commands,
however, may be overridden by commands at the job or JDE
level.
NOTE: The JDL level is the highest level in a JSL. When you
enter the following command levels, you may wish to indent
them under the system level commands.

Coding system level commands with identifiers

System level commands that require identifiers are typically
coded first. These commands must be placed in the JSL either
before or in the same job as any other commands within the
library that reference their identifiers. The identifier that begins
the command is typically placed at the left margin (at the
beginning of the line).
