PDL principles and procedures1-26 Using LCDS Print Description LanguageCatalog level commandsThe catalog level allows the coding of commands common toseveral JDEs. A catalog can then be referenced in an INCLUDEparameter in any following JDE commands. A catalog section ofa JSL begins with the CATALOG command and ends with theappearance of another CATALOG command or a JOBcommand. CATALOG commands may contain the samecommands that appear in the JOB command.The CATALOG command has the form:catname: CATALOG;The CATNAME is a 1 to 6 character alphanumeric identifier, ofwhich at least one character must be alphabetic. The catalogname is referenced by JDEs after the CATALOG command sethas been defined.For example:POWER: CATALOG;In this command, POWER is the catalog level identifier to beused in the INCLUDE parameter of a JOB command. Toreference the catalog named POWER in a job, the job levelcommand would be:JOB1: JDE INCLUDE=POWER;Job or JDE level commandsA JSL contains one or more elements called “jobs” or “JobDescriptor Entries.” A JDE, along with its system levelcommands, describes the options that apply to one printing task.A JDE contains one input format, one set of processinginstructions, and one set of output instructions. The identifier foreach JDE (job) is a user defined name that you invoke to run thejob.PDL commands that are coded within the job command leveloverride the system commands. For each job, values notspecified in any of the command sets are taken from the PDLdefaults. (Refer to the “PDL command and DJDE summary”table in appendix A for a list of all command defaults.)PDL commands coded at a catalog command level can beincorporated as shown in the command syntax below.CATNAME is a 1 to 6 character alphanumeric identifier of apreviously defined catalog name.
