Using logical processing
Using LCDS Print Description Language 3-51
• Interaction with RSTACK
– A record that satisfies the RSTACK criteria is detected,
and it terminates the report and record suspension,
regardless of whether or not the printing of records was
suspended at the time.
DJDE records are not processed if record printing has
been suspended. Refer to the “Using Dynamic Job
Descriptor Entries (DJDEs)” chapter for further
information.
– If the criteria for RSTACK and RSUSPEND are satisfied
on the same record, that record delimits the report, and
the record is suspended.
• Make sure that, if an RSUSPEND command is coded, an
RRESUME command is also present for the job. A warning is
issued by the XJDC compiler if one, but not both, commands
is invoked for a job. However, the JDE is compiled as
programmed.
• If a data record satisfying the test expression in the
RSUSPEND is encountered, printing is suspended. If no
record that satisfies the test expression in the RRESUME
command is encountered (or no RRESUME command is
present for the job), there is no output generated for records
that occur after the point of suspension.
• Record selection or deletion is performed before RSUSPEND
or RRESUME processing. If a record satisfying either the
suspend or resume test criteria was not selected for or was
deleted from printing, it does not cause either the suspend or
resume function.
• The records just before print suspension and after
resumption should have compatible printer carriage control
(PCC) characters. No additional carriage control characters
are inserted by the system during the print suppression.
• Use of the LINENUM parameter in the CRITERIA command
is not recommended when using RRESUME. Because
carriage control characters are not processed during print
suppression, the line number used by the system is that
which existed before the suppression started. This could
result in the test criteria being either unexpectedly satisfied or
never satisfied as a function of the line number where the
print suppression started.
