... log_exp1 OR log_exp2 OR log_exp3 ...


If multiple logical expressions log_exp are joined using with OR, a new logical expression is created which is true if at least one of the logical expressions log_exp is true. The join is false only if all logical expressions are also false.


  • The operator OR provides a weaker join than NOT and AND provides a stronger join than EQUIV.

  • The operator OR implements a logical OR join. Negating a join of this type using NOT is the same as a NOR join (Not OR). It is true if all expressions are false.
