UltraCalcFunctionOr Class

Logical-OR returns the boolean value, TRUE, if at least one argument has a value of TRUE. When all arguments are FALSE, then this function returns FALSE.

Remarks

OR(boolean1, boolean2, ...)

Boolean1, boolean2, ... are a list of boolean (TRUE or FALSE) values or conditional statements (any UltraCalc expression which itself evaluates to a boolean TRUE or FALSE value) to be evaluated for the constraint that at least one argument should be TRUE (or conversely, that all arguments should be FALSE.)

All arguments are tested (i.e., the logical-OR function does not use "short-circuit" evaluation, in which the function can stop executing as soon as the first argument having the boolean value, TRUE, has been processed.)

This function stops evaluating immediately when any argument results in an error value. An error value is neither TRUE nor FALSE, therefore the return value of the logical-OR function is undefined.
