Just reread. Sorry, scratch the OR. (head still not functioning on all cylinders). Problem in your questions is still the difference betwen if() and iif(). iif is not "double if" but "immediate" if. Maybe that's what's causing your confusion.

Yes, you can use OR. However, I did not correctly understand what you were after and wrote the IIF too quickly and incorrectly, as Graham noted. I think your basic problem is confusion about if(...) and IIF(...) which is explained in the Users Guide.

Thanks Bill. Yes my IIF() is wrong. I know that. That's what I told you in my email. And yes in the AFL User Guide there is a short part called 'Common Coding Mistakes' but this only gives a very simple use of the double IIF. Not what I am asking for. That's the reason why I told you in my email that it's rather frustrating that I cannot find the syntax ...
Although your code does not give me anymore syntax errors, I have a very strange feeling when looking to those 'AND's. Any idea what would happen when I replaced the AND's by OR's ? And why do we need those AND's where in a normal IF we are using brackets ?
Anyway as far as I can see it works from a syntax point of view. Thanks again ...
Ton.

Your use of IIF() is wrong - Users Guide "Common Coding Mistakes." If I correctly understand what you are after then this should work:
x = iif(barnum < 21, highbar = c and lowbar = c and range = c, null);
