10.8 Programming a Report Writer Report
In the preceding example, the value of ADD-COUNTER is added to the
CONTROL FOOTING FINAL counter every time the FIRST-DETAIL-LINE
report group is generated.
10.8.12 Restricting Print Items
In a Report Writer program, the GROUP INDICATE clause eliminates repeated
information from report detail lines by allowing an elementary item in a DETAIL
report group to be printed only the first time after a control or page break. The
following example illustrates the use of this clause:
01 DETAIL-LINE TYPE DETAIL LINE PLUS 1.
05 COLUMN 1 GROUP INDICATE PIC X(6) VALUE "SALES:".
* (prints only the first time after a control or page break)
05 COLUMN 10 PIC X(10) SOURCE BRANCH.
* (prints each time)
These statements produce the following lines:
SALES: BRANCH-A
BRANCH-B
BRANCH-C
The next two examples are nearly identical programs; the only difference is the
use of the GROUP INDICATE clause in the second example.
The following program does not contain a GROUP INDICATE clause:
01 DETAIL-LINE TYPE IS DETAIL
LINE IS PLUS 1.
02 COLUMN 1 PIC X(15)
SOURCE A-NAME.
02 COLUMN 20 PIC 9(6)
SOURCE A-REG-NO.
It produces the following output:
123
