Thanks for the remarks all.

Shabaz, your function will work as well. I guess I am just in the habit of testing for valid results, not invalid. Your code reflects a conversion of my formula from sum of products (/a/b + c) to product of sums (a+b) AND /c. The production code will contain enough of an explanation to allow me and anyone else to understand what the function is doing. I have way too many projects and will most likely not remember this function within a few months.

Mcb1. In boolean algebra, the "+" operator is commonly used to denote an OR operation as a dot at mid height represents a AND operation. Having the formula /a/b + c is the same as saying not a AND not b OR c. Perhaps a bit clearer would be ((not a) AND (not b)) OR c. I hope I've answered your question since I am not sure if I understood it. Salvador

Never did study that, and during my training the Logic course was the worst.

Looking at your truth table it seems that whenever c=1 its valid or when a,b and c = o its valid.

You might want to expand on how you got from the formula to the expression ( ie how does '+ c' translate to an OR)

very useful thanks for sharing
