DATA: TEXT1(30) VALUE 'This is the first text',
TEXT2(30) VALUE 'This is the second text',
TEXT3(30) VALUE 'This is the third text',
STRING(5) VALUE 'eco'.
IF TEXT1 CS STRING.
WRITE / 'Condition 1 is fulfilled'.
ELSEIF TEXT2 CS STRING.
WRITE / 'Condition 2 is fulfilled'.
ELSEIF TEXT3 CS STRING.
WRITE / 'Condition 3 is fulfilled'.
ELSE.
WRITE / 'No condition is fulfilled'.
ENDIF.
产生如下输 出：
Condition 2 is fulfilled.
这里，第二个逻辑表达式 TEXT2 CS STRING 是真，因为字符串“eco” 存在于 TEXT2 中。
