Tereza, it's my opinion that <> ought to have worked as well, as it works with other forms of non-numeric data, like strings. I think it's something that slipped by the developers. I would eventually have encountered the same thing. In fact I did encounter a similar kind of thing when checking to see if an array variable was empty, in order to determine if, say anything was returned by a database call. All array variables seem to be empty, whether there is an array there or not.
I give you this: put "test" into myArray[1];put empty into myVar;put myArray = myVar returns true. BUT put "test" into myArray[1];put "test2" into myVar[1];put myArray = myVar returns false. THAT is frickin UGLY crazy! Bob On Sep 20, 2011, at 9:26 AM, Tereza Snyder wrote: > NO you cant: > > (from the docs) > > Note: Arrays in LiveCode are un-ordered.
