I have been looking at Prolog Predicate code and making an artificial intelligence choice.

Example here: http://www.ifcomputer.co.jp/en/manuals5.2/uguide/node15.html

I am wondering if VFP's IIF() can be used the same way for in a simlar way.

From VFP Help:
Returns one of two values depending on the value of a logical expression.
IIF(lExpression, eExpression1, eExpression2)
