PDL principles and procedures The Job Source Library (JSL) The PDL commands that you issue to the printing system must be entered together in a file called a "job source library" (JSL). The JSL file is then compiled to convert it to an object file called a "job descriptor library" (JDL), which the system can read. The printing system then responds to the commands contained in the JDL file and prints the job the way you want it to appear. You create a JSL by entering PDL commands at either of the following: • Your host computer, using a host based editing facility • Your print server, using the UNIX Text Editor You can store your JDL files for different jobs on the print server internal disk, from which the system retrieves the JDL specified for the job. You can also store JDLs and JSLs on diskette, cartridge tape, or open reel tape and import them to the disk when you are ready to use them. In order to create a JSL you need to know the following: • What a JSL specifies • Before creating a JSL: considerations and decisions • How to code a JSL • How to compile a JSL into a JDL • Compatibility of the DP with other LPS that use PDL commands Using LCDS Print Description Language 1-17
