Incorrect Statement After CASE

In ABAP Objects WHEN must be the first statement after CASE
.

Error message in ABAP Objects if the following syntax is used:

CASE a.
MOVE 5 TO a.
WHEN 5.
WRITE a.
ENDCASE.

Correct syntax:

MOVE 5 TO a.
CASE a.
WHEN 5.
WRITE a.
ENDCASE.

Reason:

The CASE control structure must always reflect the semantics of an IF - ELSEIF control structure, which is not ensured if a statement could occur between CASE and WHEN .
