Obsolete Syntax
CASE ... 
  statements 
  WHEN ... 
    ... 
ENDCASE.
Effect

CASE and the first statement WHEN
work in the same way as when they are specified directly in front of CASE.
This construct is not allowed in classes and produces a syntax warning outside of classes. The statements must be placed in front of CASE.
