Job source library (JSL) structure
To simplify JSL coding, PDL commands are grouped into command
levels. The use and syntax of command levels, along with the
required END command, are defined in the following sections:
•
ID level
• System level
• Catalog level
•
Job or JDL level
•
END command
The command levels are always preceded by the JDL coding, which
provides the name of the compiled JDL.
Command levels
You can place PDL commands in any command level, depending on
your particular application needs.
Table 2-3 outlines the command levels and some typical
specifications that are included in these various levels.
