- Ded was originally written for CP/M-80 systems. File 'ded.doc' is a
- description of that version. The version for the Amiga is different in
- the following ways:
-
- - the program to configure Ded for different key bindings has not
- yet been ported. Thus, you are currently stuck with the bindings
- described in 'CommandList'.
-
- - the ability to handle multiple windows on the screen has been
- added. The only documentation for these new commands is their
- presence in the command list. Most of them are pretty
- straightforward, however. Note that Ded cannot currently handle
- having multiple windows into the same buffer.
-
- - file I/O in Ded is currently a bit slow. This is because it uses
- Draco's I/O system in a portable way, and that I/O system is
- produced by the current compiler and so isn't very efficient.
- The big cost is the register save/restore on procedure entry/
- exit.
-
- - Ded's use of the Amiga screen is via my CRT library. This results
- in quite fast screen updates, scrolling, etc. I usually run Ded
- in the background and use the window forground/background
- gadgets to switch between Ded's window and the AmigaDOS window.
- The window sizing gadget is present, but Ded doesn't know about
- it, so don't touch it (Ded won't crash or anything, but it
- doesn't understand about it's "screen" changing size). If you do
- fiddle with it use ESC-r to redraw the screen.
-
- - Ded currently doesn't handle lines longer than it can display on
- the screen. This is currently 79 characters. I know how to fix
- this fairly easily, but haven't done it yet.
