!AWOct93/Goodies/Disc/Example3/!DeskApp/!Help
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.

File contents
Program : !DeskApp
Purpose : To illustrate how parameters are passed to applications
Usage : Method 1:
---------
Double-click the Acorn application !TinyDirs. This places
a blue folder on the left-hand icon bar.
Now drag !DeskApp onto this folder. The icon will change to
that of !DeskApp.
When a file is now dragged onto this icon its full path name
is printed.
Method 2:
---------
Place !DeskApp in a directory from where it can be called
as a *command (e.g. CSD, library, or see !Extend).
Now type
*!DeskApp <parameter list>
Explanation : Obvious. Examine the !Run file of !DeskApp.
