This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

ClickDir, version 0.10
======================
The Application
---------------
For some reason, everyone seems to want to write an application to set the
current directory, usually by dragging files to an icon on the icon bar.
Now, I've never seen the point in this, being quite happy to type the
directory name in the shell. However, inspiration struck for a new way of
setting the current directory, and since it was such a small piece of code,
I wrote it.
What it did was to change the directory *every* time a file or directory was
double-clicked in a Filer window. Unfortunately, this proved to be less than
useful, since you could be anywhere when you went into the shell. So, this
is a new improved version, which has two modes of operation, one shot and
automatic. Automatic works like the original - the directory is changed on
every double-click, which is useful for running simple (non-desktop)
programs from the Desktop. To change the directory in one shot mode, you
first have to click the ClickDir icon (on the icon bar) - this is useful
when working in the shell. There is a menu on the icon to switch between
modes (and quit).
The program starts up in one shot mode (the most useful).
Double-clicking directories will set the current directory to the directory
clicked, double-clicking any other files will set it to the directory
containing that file.
The Program
-----------
The program is written in ARM code. The directory contains the following:
!Boot
!Help - this file
!Run
!RunImage
!Sprites
CreateRI - source code
Templates
Please report any bugs/improvements to me at one of the addresses below.
If anyone finds it useful, I may turn it into a module thus making it a
little more permanent (in theory, it should also be smaller, but since RMA
space is very difficult to recover, this is probably a false economy). I
would prefer to do this myself, so that there can be a definitive version,
but if you must do it yourself, might I recommend using Richard Lloyd's
Trashcan module as a base (I probably will).
Finally, here's a quick resume of how it works (in automatic mode):
Repeatedly listen for User Message event
If Message_Quit, then closedown and quit
If Message_DataOpen, then use the filename given to set the
directory. Do *not* reply to the message.
