Re: [amibroker] AFL syntax for nested IIF ?

["Ton Sieverding" <ton.sieverding@xxxxxxxxxx>]

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);
