Ada95 or Ada83?  With Ada95 it is quite straightforward (see section 3.10
of the Reference Manual).  You simply create an access type and use the
access type  as the parameter.

...
type procedure_access is access procedure (. . .);
procedure my_proc (proc_access : in procedure_access);
...
procedure real_proc (...)  -- same arguments as in the type declaration
...
my_proc (real_proc'access);

For Ada83, it could still be done for all the compilers I used, but was
implementation dependent.  As I recall, one used the 'address of the
procedure, and then used a representation clause to call the procedure.
