RSTACK Command Using Logical Processing

4.12 RSTACK Command
The stacked reports feature enables the online and offline user to define a series of reports
in a single file. This is accomplished by specifying an end-of-report condition in the coded
logical processing commands RSTACK (online and offline) and BANNER (online use only).
End-of-report is that point in processing a report when all of the pages of a copy of a report
have been formatted to disk and processing has begun on the next report.
Reports are stacked in a file if more than one report is included in a single file and separated
from each other logically but not physically (with tapemarks, operating system labels, and
so forth). In processing stacked reports, the system checks each record for the logical end-
of-report specification as defined by the TEST parameter of the RSTACK and BANNER
commands. When RSTACK is used for report separation, end-of-report occurs as soon as
the test criteria is satisfied. However, when BANNER is coded, the user specifies the num-
ber of consecutive banner pages which must satisfy the test criteria before end-of-report
occurs.
Report separation based on banner page detection is performed with the BANNER com-
mand. This includes a test expression to detect a banner page and a count of the header
or trailer pages used to separate reports. The syntax and format of the BANNER command
are described in the "BANNER command" section.
4.12.1 RSTACK delimiter modes
There are two modes of stacked reports: delimiter and non-delimiter. In the delimiter mode,
the record satisfying the TEST criteria is not part of the report following the delimiter but sim-
ply serves to separate or delimit one report from another. In the non-delimiter mode, reports
are stacked one on top of each other without any special records separating the reports.
The two modes are specified by the DELIMITER option of the RSTACK command.
If DELIMITER=YES is coded, the user may actually separate each report with multiple suc-
cessive records, each of which satisfies the TEST expression on the RSTACK command.
In this case, all consecutive delimiters are treated as a delimiter packet. In delimiter mode,
the user has the option to print the delimiter (or the delimiter packet) and to select the output
destination of this delimiter page—BIN, TRAY, or BOTH. The option BOTH delivers the
page to the sample print tray and the output tray. The delimiter page, when printed, is output
as part of the subsequent report.
All of the printing options selected in the JDL remain in effect during report delimiter printing
except carriage control, which is ignored; the carriage control is replaced by a print and
space 1 line control. If DJDE records exist within the delimiter packet or immediately follow-
ing, they are included on the delimiter page.
