Can anyone tell me the semantics of the 'mode' arg to the OPEN, CREATE
and SEEK traps?  I'm looking for enlightenment on how to do things like:

  open an existing file for output, position to end
    "   "    "       "   "    "        "      " beginning
  open existing file for bidirectional IO, position randomly
  create new file for bidirectional IO...

ad nauseum.  Thanks in advance for any info.
