IDEN Command

5.2 IDEN Command
To invoke DJDE processing, an IDEN command must be coded in the JDL. This command
notifies the system that DJDE records may be part of the input data stream. It also de-
scribes the search criteria for locating and identifying DJDE records. The DJDE record (or
records) 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 ac-
tive JDE) and a series of parameters that describe the actual JDE changes to be applied to
the report.
The IDEN command (coded in a user's JDE) notifies the system that a DJDE record (or
records) may be part of the input data stream. The command also describes the character-
istics of a DJDE record so the system can identify and locate any DJDE records.
An example of a coded IDEN command is:
IDEN PREFIX='RTEST', SKIP=9,OFFSET=3;
The PREFIX parameter defines the character string which must appear in the identification
part of each DJDE record in the input data stream. When the system recognizes this char-
acter string (in the example, 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.
Example:
IDEN PREFIX=E'DJDE', SKIP=7, OFFSET=2;
Parameter

Definition(s)
value
specifies the number of bytes (beginning at 0) from the beginning of the user
portion of the record to the beginning of the prefix string constant of the DJDE
record. It may be a negative number.
The default is 0.
sc
Any records within the data stream which contain an identification field equal
to the specified prefix string sc are recognized and processed as DJDE
records.
There is no default.
value
Specifies the number of bytes (beginning at 0) from the beginning of the user
portion of the record to the beginning of the DJDE parameters. It may be a
negative number.
The default is 1.
