DVF: dlls remembering allocatable arrays

I am writing Windows dll's in DVF 6 for a Delphi front end. This
particular dll needs to be left in memory and called multiple times. I
want to create and load some allocatable arrays on the first call to
the dll, then use the data on subsequent calls to the same dll. Even
though I use the "SAVE" attribute for the arrays, the data disappear
between subsequent calls. Not so for simple variables -- those are
remembered. Btw, the front end doesn't need or use the data needed by
the dll.

I'd greatly appreciate a tip on how to make the data in allocatable
arrays accessible on subsequent calls to the dll.

Thanks very much,
Bruce
