The following example shows that you can code multiple WHEN phrases if several conditions should lead to the same action. Doing so gives you more flexibility than using only the THRU phrase, because the conditions do not have to evaluate to values in a range nor have the same class.
EVALUATE MARITAL-CODE
WHEN "M"
ADD 2 TO PEOPLE-COUNT
WHEN "S"
WHEN "D"
WHEN "W"
ADD 1 TO PEOPLE-COUNT
END-EVALUATE
The following nested IF statements represent the same logic:
IF MARITAL-CODE = "M" THEN
ADD 2 TO PEOPLE-COUNT
ELSE
IF MARITAL-CODE = "S" OR
MARITAL-CODE = "D" OR
MARITAL-CODE = "W" THEN
ADD 1 TO PEOPLE-COUNT
END-IF
END-IF
