>I am having some fun learning neural networks. I have the formula below with which to contend. As you can see, there are two (2) equal signs. Is a two equal sign formula legal in VFP 8 SP1? I have initialized all the variables and they are numeric. Even so, X2 evaluates to .F. instead of a decimal number.

Grady,

As others have said the expression to the right of the first equal sign is a logical one. In my experience, which covers a fairly large number of languages, whatever language will consider the expression exactly the same as VFP does. When doing this sort thing (which I use quite a bit), it's a good practice to use open and close parenthesis around the expression to the right of the first equal sign. This helps to clearly indicate that the result is a Boolean.
