Table 73 describes the type of operand allowed for each unary operator and the type of the result. Table 74 describes the type of operands allowed for each binary operator and the type of the result. Table 75 describes the type of operands allowed for each built-in function and the type of the result. Prototyped procedures support whatever data types are defined in the prototype definition.
