4.2 Initializing Values of Table Elements
4.2 Initializing Values of Table Elements
You can initialize a table that contains only DISPLAY items to any desired value
in either of the following ways:
• You can specify a VALUE clause in the record level preceding the record
description of the item containing the OCCURS clause.
• You can specify a VALUE clause in a record subordinate to the OCCURS
clause.
Example 4–11 and Figure 4–10 provide an example and memory map of a table
initialized using the VALUE clause.
Example 4–11 Initializing Tables with the VALUE Clause
01 A-TABLE VALUE IS "JANFEBMARAPRMAYJUNJULAUGSEPOCTNOVDEC".
03 MONTH-GROUP PIC XXX USAGE DISPLAY

If each entry in the table has the same value, you can initialize the table as
shown in Example 4–12.
Example 4–12 Initializing a Table with the OCCURS Clause
01 A-TABLE.
03 TABLE-LEG OCCURS 5 TIMES.
05 FIRST-LEG PIC X VALUE "A".
05 SECOND-LEG PIC S9(9) COMP VALUE 5.
In this example, there are five occurrences of each table element. Each element
is initialized to the same value as follows:
• FIRST-LEG occurs five times; each occurrence is initialized to A.
