God that's kludgy, but if it works it works, eh? Still, I wish Allaire
would put a more "standardised" and documented syntax, so I wouldn't have to
scratch my head as much. :)

Subject: Re: What I want in CF (was: Learning ASP)
>Cold Fusion is weak in these areas, but really you can do all these things
(or "emulate" them :-) ) using existing features.
>(forgive my syntax - I'm writing this quickly)
>
>Pick a standard variable name, like ReturnValue and only use it for
returning a value from a custom tag:
> caller.ReturnValue = xxx
>
>Or use the tag's name as a structure:
> If NOT IsDefine("MyTagName") {
> MyTagName = StructNew()
> }
> MyTagName.Return = "some data"
>
>
>Static variables: How static do you want them? :-) Cold Fusion has extra
"scopes" that wouldn't make sense in a standard programming language like
C++ where the application all runs at once. In Cold Fusion you might want
static variables that retain their value (1) for the entire Application, (2)
for the page request (there are more you could define if you tried hard).
>Pick a standard word, for example "static" and keep them under Application
and Request. Use a hash of the module name:
>
>In Application.cfm:
> If NOT IsDefined('Request.Static')
> Request.Static = StructNew()
>
>In module: MyTagName:
> Request.Static["MyTagName"] = StructNew()
> Request.MyTagName.ThisStaticVar = "some data";
>
>This is now a static variable that will retain it's value for the duration
of this page request through all files and multiple calls to this tag. It is
only "private" within the tag because you make it so with the naming
convention. The same thing can be done under the Application scope (scopes
are structures).
>
>Now the *REAL* problem with Cold Fusion is there is no ability to define a
macro, function, or subroutine to "hide" these details so these kinds of
things are very wordy which encourages mistakes when you have to specify
them a hundred times.
