  16 bit MSDOS from 16 bit MSDOS?  32 bit from 32 bit?  16 bit
or 32 bit DOS from Windows 3.1, or Windows 95, or Windows 2000?
One machine starting a program on a separate machine connected
over a network?  Using which vendor's custom Ada library?
  Since you can't call DOS executables on IBM mainframes, or in
a pocket GSM system, there clearly can't be a standard way to do
it across all vendor's Ada systems on all target systems.  So
you'll have to be more specific about what you want.

In general, you can execute a shell command from an
Ada executable by means of an interface to the "system"
function from the C runtime library.

Here is a library-level procedure that does just that

with Interfaces.C;
function Execute_Shell_Command (The_Command_String : String)
      return Interfaces.C.Int is
   package C renames Interfaces.C;
   function System (S : C.Char_Array) return C.Int;
   pragma Import (C, System, "system");
begin
   return System (C.To_C (The_Command_String));
end Execute_Shell_Command;
