Re: IsDefined and brackets

Thanks to everyone who replied. I knew I could use isdefined(aStruct.aField) but I was just wondering what the rationale was behind invalid syntax error for isdefined(aStruct['aField']). Dave's explanation that I should really think of it as two separate tests was pretty good. Also, I don't

: Thursday, April 18, 2002 9:04 AM Subject: RE: IsDefined and brackets I believe that IsDefined is only meant to check for the existance of top level variables, for complex data types you have to use the specific functions for each type. So here CF is trying to find out if there is a variable

RE: IsDefined and brackets

Why not simply cfif isdefined(aStruct.aField) ? I implied in my original post that you could use dot notation, as opposed to array syntax. If you use dot notation, it's clear that you're referencing a variable within a structure, I suppose, which entails checking the existence of both the
