Why doesn't bbSystemPropety( ) Work?

Hi, I modified my BlitzMAX Module to return system properties, but all it does is return the same number no matter what value I use. So, the question is, is this command broken?

In Blitz3D SystemProperty() returns a string.

So if you had a working bbSystemProperty() it would be a string, not a number.

it doesn't work that way either, for example...

Global dir:String = String.FromCString( bbSystemProperty("tempdir") )

Doesn't work.

I think the declaration should be somewhat like this:
Function bbSystemProperty$z(name$) = "bbSystemProperty"
However, there is a good chance that the systemproperty function isn't included at all.
