Newbie here. I'm a little puzzled by some features of the Reference manual. Eg for "if" (if 'any1 any2 . prg) -> any What is the significance of "any1" being quoted and "any2" not being quoted? I also don't get the "." between "any2" and "prg" - does that mean something? Is there any significance in the difference of "any2" and "prg". I would have thought they were both "any" type parameters. Thanks Jonathan.
