ReadOnlyFlg to just after the test for an open notefile. Otherwise, a
notefile opened read-only could be changed to one opened normally. Also
added Read-only% Open to NC.NoteFileIconOpenOperations - if you can open
an open notefile, you should be able to open a read-only notefile
(both operations simply flash the icon instead of attempting to open the
notefile))

(* * fgh 5/23/86 Renamed to NC.OpenNoteFile from NC.OpenDatabaseFile. Total revamp to implement device vector.)
(* * kef 7/18/86: Inserted a call to stuff the UID into the NoteFile because BuildHashArray needed it.)
(* * kef 7/21/86: Moved up the install of the NoteFile into the NoteFileHashArray to before the building of the
NoteFile's hash array. The reason is that the remote multi client build hash array function needs to get a list of
UIDs, and in order to do this, it needs to grab a Courier stream for the NoteFile given only the UID.
It can only do this if the UID is registered in the NoteFilesHashArray.)
(* * fgh 8/31/86 Updated to account for changes made to system since 5/23/86 revamp. Changes reimplemented include:
(fgh 6/8/86 Added code to insure that two files with SameUIDP would never be open at once.)
(fgh 6/25/86 Added contention locks -- NC.ProtectedNoteFileOperation, Don'tCheckOperationInProgressFlg etc.)
(fgh 6/27/86 Added MenuPsotion arg to pass to SetUpNoteFileInterface) (kirk 15Jul86 Added call to
NC.SetUpNoteFileInterface if already open))
(* * fgh 9/1/86 Reimplemented ReadOnly NoteFile open.)
(* * fgh 9/4/86 Put in default for NoteFilesHashArray which is NC.NoteFilesHashArray)
(* * kirk/rht 8/29/86: Now resets Name after conversion from version 2 to version3.)
(* * rht 10/29/86: Changed "aborted" to "canceled" in message.)
(* * rht 10/31/86: Added Don'tCheckForTruncationFlg arg.)
(* * rht&pmi 11/21/86: Took away the protection from around the AFTER call to open events fns.)
(* * pmi 12/12/86: Added InterestedWindow argument to NC.SetUpNoteFileInterface so that it can print a prompt to
the user about placing the NoteFile menu.)
(* * rg 3/4/87 Added NC.ProtectedSessionOperation wrapper, removed Don'tCheckOperationsInProgressFlg)
(* * rht 3/25/87: Now calls NC.CoerceToInterestedWindow.)
(* * pmi 3/31/87: Moved line of code which sets the ReadOnlyFlg to just after the test for an open notefile.
Otherwise, a notefile opened read-only could be changed to one opened normally.)
