Output processing task
Print description language (PDL) processor
Forms description language (FDL) processor

The report task works in connection with the input task. It records the
disk addresses of the font, form, and image files to be used for the
job. The result is a page buffer and a page log for each page to be
printed. The page buffer consists of the variable data and print
instructions for the page. The page log consists of tracking
information used in processing the page.
The dynamic job descriptor (DJD) task compiles the dynamic job
descriptor entries (DJDE) in the input data stream. The DJDEs give
the LPS instructions for printing based on IDEN command parameter
specifications in the input data stream.
The output processing task uses the page logs written by the input
task to load fonts, graphics, and variable data in the Advanced Image
Subsystem (AIS). It coordinates the activity of the AIS with the
printer. In addition, output manages delivery of the printed pages to
the correct bins, performs page recovery if necessary, and performs
accounting functions.
The PDL compiler compiles an ASCII job source language (JSL) file
into object code and saves it as a job descriptor library (JDL) file. It
also creates ancillary files like PDE, CME, STK, LIB, etc.
The FDL compiler compiles an ASCII form source language (FSL)
file into executable object code and saves it as an (FRM) form file.
