I'm not familiar with GNAT (I know, you were answering Dewar...)

Do you mean that you want to be able to modify the formal parameter?  (But if
that were the case, why is Address_To_Access_Conversion the workaround, instead
of just declaring a variable and assigning it the parameter value?)  Or do you
mean you want to modify the actual parameter, as if it were mode 'in out'?
