10.8.4 Describing Report Group Description Entries
In a Report Writer program, report groups are the basic elements that make up
the logical page. There are seven types of report groups, which consist of one or
more report lines printed as a complete unit (for example, a page heading). Each
report line can be subdivided into data items or fields.
Table 10–1 lists the seven types of report groups:
Table 10–1 Report Writer Report Group Types
Report Group Type Description
REPORT HEADING Prints a title or any other information that pertains to the
entire report
PAGE HEADING Prints a page heading and column headings
CONTROL HEADING Prints a heading when a control break occurs
DETAIL Prints the primary data of the report
CONTROL FOOTING Prints totals when a control break occurs
PAGE FOOTING Prints totals or comments at the bottom of each page
REPORT FOOTING Prints trailer information for the report
A Report Writer program can include both printable report groups and null report
groups. Null report groups are groups that do not print but are used for control
breaks.
Figure 10–9 shows the report group presentation order found on a logical page.
You must code at least one DETAIL report group (printable or null) in your
program to produce a report. All other report groups are optional. Note that you
can code a report group by using the abbreviations shown in Figure 10–9.
