PDL principles and procedures
Using LCDS Print Description Language 1-3
Refer to the “Specifying DJDE records” section of the “Using
Dynamic Job Descriptor Entries (DJDEs)” chapter for information
on how to include DJDEs in the data stream.
PDL command structure and components
In order for the system to recognize and respond correctly to
your PDL commands, you must construct and enter them
correctly. Some components of PDL commands must be
specified every time, while others are optional. There are some
rules for constructing commands. You must follow these rules in
order for your system to print your job the way you want it. Refer
to “Command syntax” later in this chapter for details on the JSL
syntax rules.
Command lines
The JSL consists of command lines, also called records, on
which you enter PDL commands. The length of these records
can be up to 133 characters for JSLs on tape.
NOTE: If you select the [TRUNCATE] option of the xjdc
compiling command, only characters 1 through 72 may be used
for parameter information. Refer to “Compiling a JSL” later in this
chapter.
You can continue commands on successive lines if the
parameters are separated by commas. Multiple commands may
appear on one record line if separated by semicolons.
Components of a command
Each PDL command consists of a command keyword and one or
more parameters. Parameters are separated by commas or
spaces. A PDL command has the following parts:
•
Command identifier (if required)
NOTE: DJDEs do not have identifiers.
• Command keyword
• One or more command parameters
• Parameter options
