10.8 Programming a Report Writer Report
10.8.13.2 Generating a Report Writer Report
The GENERATE statement prints the report.
You can produce either detail or summary reports depending on the GENERATE
identifier. If you code the name of a DETAIL report group with GENERATE, you
create a detail report; if you code a report name with GENERATE, you create a
summary report.
10.8.13.3 Automatic Operations of the GENERATE Statement
When the first GENERATE statement is executed, the following report groups
are printed, if they are specified in the program:
• REPORT HEADING report group
• PAGE HEADING report group
• CONTROL HEADING report groups
• For detail reporting, the specified TYPE DETAIL report group
A USE BEFORE REPORTING declarative can also execute just before the
associated report group is produced, to produce a cover page for the report, for
example.
Note
Figure 10–11 and Figure 10–12 illustrate the major flow of operations,
but do not cover all possible operations associated with a GENERATE
statement.
Figure 10–11 shows the sequence of operations for the first GENERATE
statement.
