Dynamic Job Descriptor Entries (DJDEs)
5.5 DJDE Record Specification
DJDE records are created by the user as part of the data stream. The system looks for them
only if a DJDE prefix has been specified by an IDEN command within the JDL used to pro-
cess the job. DJDE information is contained in one or more records, each of which may be
up to the maximum record length specified for the job input data. For each DJDE record,
the prefix (the identification field) must begin in the same location in the record. DJDEs are
terminated by an END parameter in the last DJDE record. All specified DJDE information
is applied at the next record or page boundary after the END parameter is encountered.
There may be multiple DJDE sequences in a job. Each set modifies only the specific pa-
rameters mentioned within the DJDE.
The following should be considered when preparing DJDE records as part of the input data
stream.
•
The DJDE record may contain more than one parameter. Each parameter within a
record must be separated from the next parameter by a comma.
•
Lowercase alphabetic characters are not accepted in the DJDE parameter line. If they
are used, a DJDE syntax error message is displayed.
•
The end of a DJDE record parameter that is split and continued on the next DJDE
record should be terminated with a ,; (comma, semicolon).
•
The prefix in the DJDE record may appear after the DJDE parameter(s) as long as it is
consistently located in all DJDE records.
•
DJDE records need not be consecutive since none of the parameters are applied until
END; is encountered. However, it is recommended that DJDE records be consecutive,
especially when used with delimiter records. To optimize input processing speed, DJDE
parameters should be grouped into as few records as possible. A group of DJDE
records terminated by an END parameter is called a packet.
•
Only one page-oriented packet can be deferred to the next page. If a page-oriented
DJDE packet is received after the start of page A so that it is deferred to page A+1, any
separate DJDE packets following it on page A may cause unpredictable results and
may possibly be printed as data.
•
A page-oriented DJDE positioned prior to any print parameters on a page takes effect
on the current page. A page-oriented DJDE positioned after the first print parameter on
a page takes effect on the next page, unless end-of-report is encountered.
•
For delimiter mode stacked report processing, DJDE parameters may be placed in the
report body. They may also be placed within or after (but not before) the delimiter record
packet.
