•
There is no change in the maximum record length when
processing interleaved graphic records. However, every record
of an online interleaved graphic must have an appended
terminating character which is the same for all records of the
graphic. If an interleaved graphic record is encountered which
does not have the same terminating character as the first
record of the graphic, the user has the option of aborting or
continuing the report. If the report is continued, the graphic is
unprintable and the results may be unpredictable.

The input data stream format must comply with the following rules:
•
Even though a JDE specifying batch mode is in effect, the first
graphic must be preceded by a DJDE specifying
BATCH=START. The last graphic must be followed
immediately by a DJDE specifying BATCH=END. These batch
stream delimiters are necessary to distinguish banner page
data (header and trailer) from graphic data.
