Ah, here's the big secret to Ada string processing: treat them as arrays.

Make liberal use of things like 'First, 'Last, 'Length and don't assume 
your 'Fists = 1. Also, remember the difference between constrained and 
unconstrained --
  D : String;                    -- Unconstrained.
  E : String := "This."          -- Constrained by initialization.
  F : String(1..255);            -- Constrained by subtype.
  G : String := Fn(X);           -- Constrained by initialization.

  -- the last thing to remember is that strings are perfectly sized for 
their content. (This should be done at initialization.) TED explains it
