THINGS TO DO -- INTERNAL
=====================================================================

IN PROGRESS / DONE

0.12	gFind should start with the kids.

0.09	Make sure CONVERT can handle both read and write to iRMX.
	The name-fixing and verification stuff should go into dirs.c
	and irmx.c.

0.07	gRead shouldn't automatically close (open's ok).

0.07	gSeek and gTell for Dirs.  gSeek needs xPrvBlk for speed.

0.07	FileViewer:  use two buffers for efficiency.  All clones of a
	viewer must share the same set of buffers.  Sort of a
	bidirectional stream.

0.07	gOpenFile(dir, mode) now exists.  Maybe ought to go into
	gOpen, but save that for later.

MUST DO:

	We may get into trouble if there is more than one iRMX
	disk in the system.  Too much use of dDrive and curVolInfo. 
	Stash current volume info in XFile or Dir (or make root a
	separate class).


OUGHT TO DO:

	Open: If you create the node first, you don't need to specify
	ascii/binary/whatever.	(On the other hand, std. C specifies
	the stream ops, not the handle ops.)

	Conversion should be generalized using filetype table and
	registered converters.

	Move buffer stuff into Dirs?

	Generic stuff ought to go into ../LIB, and get used in RD7 as
	well.

	Add gRename, gUnlink to Dir class.

	Read, write, seek, tell, etc. should take a file handle 
	(magic cookie) as an arg.  Eliminate dir.file field.

	Should separate DOS-specific stuff into yet another file,
	which would simplify a Unix port.  Mostly directory handling. 
	Could use the BSD directory routines.

	Parametrize filetypes and filesystems better.  Use tables 
	instead of enum	type and switch stmts.


	Menus for Dir and File views should depend on the filesystem. 


	The error message view should be a Text view.  This would
	allow Help view to be re-written, and also let errorPrintf
	output multiple lines.  Vertical centering flag would help.

	Make Help view take a Menu instead of an array.
	Menus:  add HELP macro, entry type.  Move screen help line
	to label string after ':'.  Make closure type (void*).


	Allow the Dir trees to be partial.  Scavenge nodes that
	aren't visible.	 (Basically an outline mode)

	Selective scavenge on Dir trees: can delete contents if 
	tcount = 0 or tcount = fcount, and not on path to dest.

	Fold changes back into RD7.  Put DISK, CONVERT, and HELP
	modules in separate directories for each product.

NOTES:

=====================================================================
DONE:
=====================================================================

0.04	Use MsgView for messages instead of InitView.

0.04	Menus.h: use void* for closure instead of char*

0.03	Split view, screen, & menu object defs into separate file.
	(this file will be almost all data, some stat & init code)

0.03	View: make more generic by separating view, which manages the 
	window and cursor location, and viewer, which traverses the
	object being viewed.

0.03	Split View.[ch] into View and Viewer.

0.03	Viewer for Drives (add filesystem, disk format to existing
	drive info (density, tracks, sectors)).

(REJ)	Drive roots probably ought to be their own subtype of Dir.
	They're pretty different, including having a different
	gHeader string.
0.03	[Alternative: use an array-oriented Viewer.]


0.02	Finish hacking main and convert for generic gReadFile,
	gWriteFile.  dCopyDosFile, etc. are now bogus.


0.01	In addition to switching file systems, make it easier to do
	so again in the future.  Parametrize things better.

0.01	Array of drive-info structures.  Compaticard?  Double-track?

0.01	Update Dir structure and disk.[ch] for iRMX-86

0.01	Split disk.c into disk.c (sector read/write), 
			  irmx.c (directory and file read/write)

0.01	Ought to have disk browser (absolute sector dump)
	Treat tracks as "files"; commands at track & drive level for
	density, sectors/track, sector size.

0.01	Investigate CopyIIpc and Compaticard boards

0.01	Change Idris -> X (i.e. something neutral)
	       rdi.c -> main.c, rdi.h -> version.h
