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.

| HideTask version 0.01 |
| Century 21 Software |
| � Dan Ellis, 1995 |
'-----------------------'
Introduction
------------
If you wish to hide a program running on the desktop then normally the
best you can do is to not give it an icon on the iconbar and give it a
null taskname. However, the null taskname still appears in the task
manager's display. This little module allows you to prevent a particular
task from appearing on startup.
How it works
------------
When a new task starts up (using Wimp_Initialise) the wimp broadcasts a
message informing any interested task of the name, wimpslot size and CAO
pointer of the new task. The task manager uses this message to produce
its list of tasks. This module applies a filter to all tasks (including
the task manager) that prevents them from hearing about the new task
starting up.
How to use it
-------------
The HideTask module provides a single SWI call 'HideTask_SetName'. Call
this with R0 pointing to the name of the task you wish to hide just
before starting the task. When the task starts it will not appear in the
task manager's list. I have used SWI number &9A6C0 but I have not yet
registered it with Acorn. If you find that it clashes, let me know and I
will get an allocation from Acorn.
