PDL principles and procedures

(Refer to “Specifying DJDE records,” later in this 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

•Comments (if appropriate)
