This is the second reply I received suggesting there is something
syntactically
wrong with conversion of an "out" parameter. However, I believe the LRM
para
6.4.1 (4) clearly states that conversion occurs in _both_ directions. As I
have
implied, this works (quite well) on every compiler I have ever used. I
have never
used GNAT, but I have used at least six other validated (Ada '83)
compilers. For
reasons I will not take time to mention, we consciously chose to avoid
declaring
intermediate variables whenever possible.

But thanks for trying...
