# operator to turn two boolean values into an integer - name inspired by the COBOL sample #

PRIO ALSO = 1;

OP ALSO = ( BOOL av, bv )INT: IF av AND bv THEN 1 ELIF av THEN 2 ELIF bv THEN 3 ELSE 4 FI;

# using the above operator, we can use the standard CASE construct to provide the #
|
|
# required costruct, e.g.: #
|
|
BOOL a := TRUE, b := FALSE;

CASE a ALSO b
