creating a 16 bit value from 2 8 bit values in Ada

[ma740988@pegasus.cc.ucf.edu (Mark)]

Could someone show me how to concatenate the Hi and Lo components? 
The end result - obviously - would be a 16 bit value.  I've waded
through my ada books here and keep coming up short?


type SOME_TYPE is 
  record 
    Lo   : BYTE;
    Hi   : BYTE;
    X    : BOOLEAN;
  -- more stuff
end record;

for SOME_TYPE use
 record
  Lo at 0 range 0 .. 6;
  Hi at 0 range 7 .. 15;
  -- more stuff
end record;  

In an earlier post i made a reference to 'intrinsics' that might aid
in my objective, but that appears to be a tartan utility.
