(* fgh: " 8-Jun-86 03:31")
(* * Open an already existing NoteFile and return a NoteFile object)
(* * rht 8/7/84: For nonexistent files, asks user whether to create unless Don'tCreateFlg is non-nil.)
(* * rht 1/9/85: Checks NC.UncachingNotCompleted global var. If non-nil, then previous notefile died unnaturally,
so we first clear junk off the IDs.)
(* * rht 8/6/85: Added Don'tTruncateFlg, which, if on, prevents the check for truncation.)
(* * fgh 10/16/85 Updated to use new cacheing scheme.)
(* * kirk 10/29/85: Now does cacheing of types and titles as background process.)
(* * fkr 11/8/85: Converted from Streams to NoteFile object.)
(* * kirk 30Nov85 Added a check for correct version number.)
(* * rht 12/6/85: Moved Kirk's above patch to NC.CheckForNeededConversion and modified somewhat.
Added check for plausible header.)
(* * rht 1/8/86: Now reuses old notefile object if there is one for this filename.)
(* * fgh 1/13/86: Fixed bug with returning File Name with embedded call to CreateDatabaseFile.
Now just calls OpenDatabaseFile recursively using result of CreateDatabaseFile.)
(* * fgh 1/16/86 Folded the cacheing of the special cards into BuildHashArray instead of making it a separate
function after the hash array is already read in.)
(* * kirk 20Jan86 Added NC.AskYesOrNo and InterestedWindow for prompt)
(* * fgh 5/2/86 Implemented before and after opening hooks using NC.OpenNoteFileFns global variable.)
(* * fgh 6/8/86 Added code to insure that two files with SameUIDP would never be open at once.)
