5. Using Dynamic Job Descriptor Entries (DJDEs) Dynamic Job Descriptor Entries, unlike the PDL commands described in the Input Processing, Print Format, and Logical Processing sections, are not coded in JSLs. They are coded in the data stream to make changes during printing to what was specified in the JSL. DJDEs are coded slightly differently from JSL statements. Using the IDEN command to enable DJDEs To invoke DJDE processing in a job, you must code an IDEN command in the JDL. The DJDE record(s) are interspersed among the data records in the input data stream. Each DJDE record contains an identification field (which matches the search criteria specified in the active JDE) and a series of parameters that describe the actual JDE changes to be applied to the report. The IDEN command notifies the system that DJDE records may be part of the input data stream. IDEN also describes the characteristics of the DJDE records and the search criteria for locating and identifying them. Example Following is an example of a coded IDEN command: IDEN PREFIX='RTEST', SKIP=9, OFFSET=3, OPRINFO=YES; The PREFIX parameter defines the character string that must appear in the identification part of each DJDE record in the input data stream. When the system recognizes this character string (in this example, it is the EBCDIC string 'RTEST'), it examines the rest of the record for DJDE parameters. The OFFSET and SKIP parameters define the starting positions of the prefix string and DJDE parameters within the record. Using LCDS Print Description Language 5-1
