   This will work, but Replace_Slice does more than intended, which is
why I recommend Overwrite.  (It is also likely that Overwrite will be
faster.)  Overwrite returns a string of the same length as the first
argument, but in Replace_Slice, the slice replaced does not need to be
the same length as the last argument. For example, 

   Txt : String(1 .. 100) := Replace_Slice(95 * Space, 50, 0, "Hello");

   will return the same string. And:

   Replace_Slice("Robert I. Eachus", 8, 9, "Iredell") replaces my
middle initial with my middle name.
