Level 88 defines a condition name, including a value or range of values that define

the condition to be tested.

Data Description Entry

A data description entry defines the characteristics of a data item. The entry can be used

in the Working-Storage Section or Linkage Section of the SCREEN COBOL program.

When the program unit is compiled, numeric elementary data items in the Working-

Storage Section that do not include an OCCURS clause are initialized to zero.

Several forms are available to describe items for various purposes. Some entries cause

the creation of items (memory space is allocated), while others supply alternative

descriptions or reference points for already existing data. Others supply specification of

value ranges for later testing.

The syntax of the data description entry is:

Format 1 is:

Format 2 is:

Format 3 is:

{ WORKING-STORAGE SECTION. }

{ LINKAGE SECTION. }

level-number { data-name-1 }

{ FILLER }
