Dave,

Call me thick, but I don't see what you are getting at...

I would expect the second to evaluate T, being evaluated from left to right because I see its alternate form as " .t. or (.t. and .F.) ". So I guess I would call it 'precedence' if one means that the "AND" word is *considered first* in relating the operands to operators, but I would still say that evaluation proceeds from left to right once those decisions have been made.

What I am trying to say is that the operators seem to be evaluated/considered in the order as documented but the actual evaluation of the expression then proceeds from left to right. Both of your examples would support that, wouldn't they?

Cheers,

Jim N
