[amibroker] Re: How to check on a variable that does not exist?

Herman,

Thanks much for the suggestion.  That's the first thing I tried.

There seems to be a lifetime issue with the static variables from the
point-of-view of what I'm trying to accomplish.

What I think I'm observing is that if a static was ever defined while
AB is open, then that definition is retained even though one comments
out the include file that did the definition in the first place.

I'm sure this behavior is desirable for many things, but in the
scenario I posit, I need the absence of the include file to definitely
create a NULL/FALSE situation.

As for VarGet() and VarGetText(), some explicit documentation on what
they return when supplied with a variable name that does not exist
would be helpful.
