EQV
Performs a logical equivalence on two expressions.
Syntax
result = expr1 EQV expr2
NOT
Performs a logical negation on an expression.
Syntax
result = NOT expression
OR
Performs a logical disjunction on two expressions.
Syntax
result = expr1 OR expr2
XOR
Performs a logical exclusion on two expressions.
Syntax
result = expr1 XOR expr2
IIF
Evaluates a variable or expression and returns one of two results based on the
outcome of that evaluation.
Syntax
Result = IIF (Expression, TrueValue, FalseValue)
IMP
Performs a logical implication on two expressions.
Syntax
result = expression1 IMP expression2
