I'm a little embarassed to be asking such a question, but I
can't figure out how to open an existing file for text-io
in such a manner as to cause the output to be appended
to the file.  Surely such an obvious function was not 
omitted ...

   There is no "official" (that is, LRM-specified) way to do this in
Ada.  It is, however, one of those things that could legally be
included in an implementation in an implementation-dependent way.
Two ways come to mind:
         1.  A form string parameter.
         2.  Ada "standard output" is defined in the LRM as never
             opened or closed explicitly by the programmer.  It sounds
             much the same as UNIX standard output and therefore could
             be appended in a UNIX system via ">>".
