6.1.6.3 Condition-Name Condition

A condition-name condition tests a conditional variable to determine whether its value is equal to any value(s) associated with the condition-name.

A condition-name is used in conditions as an abbreviation for the relation condition. The rules for comparing a conditional variable with a condition-name value are the same as those specified for relation conditions.

If the condition-name has been associated with a range of values (or with several ranges of values), the conditional variable is tested to determine whether or not its value falls within the range(s), including the end values. The result of the test is true if one of the values corresponding to the condition-name equals the value of its associated conditional variable.

X Condition-names with DBCS and floating-point values are allowed.

The following example illustrates the use of conditional variables and condition-names:

01 AGE-GROUP PIC 99. 88 INFANT VALUE 0. 88 BABY VALUE 1, 2. 88 CHILD VALUE 3 THRU 12. 88 TEEN-AGER VALUE 13 THRU 19.

AGE-GROUP is the conditional variable; INFANT, BABY, CHILD, and TEEN-AGER are condition-names. For individual records in the file, only one of the values specified in the condition-name entries can be present.

The following IF statements can be added to the above example to determine the age group of a specific record:


     IF INFANT...             (Tests for value 0)
     IF BABY...               (Tests for values 1, 2)
     IF CHILD...              (Tests for values 3 through 12)
     IF TEEN-AGER...          (Tests for values 13 through 19)

Depending on the evaluation of the condition-name condition, alternative paths of execution are taken by the object program.
