I believe I am using the AXI bindings.  For the most part, I've seen legacy
STARS packages referenced.  Not sure if they are the same.

I tried commenting out the entire exit import, but I still seem to get the
Storage_Error.  Whats interesting is that;  When I had the pragma, I could
only declare a string of 584 characters in length, and when commenting out
the entire pragma import, I can then declare a string of 624 characters in
length.  With string lengths of 585, 625 respectively, the Storage_Error
exception occurs.  This is the reason why I suspect somehow the Motif
binding is limiting the amount of stack space available for the callback
procedure.
