PD/TaskEnsure/ReadMe
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.

TaskEnsure v0.00
� Ben Summers 1993
TaskEnsure will only work properly under RISC OS 3.
What?
~~~~~
I'm sure you will all realise how useful the RMensure command is when you
want to load a module, but only if it's not already loaded. The TaskEnsure
utility allows you to do the same with a WIMP task.
I've set up my computer using various desktop boot files to set up an
environment for various tasks, for example loading printer drivers,
Impression and Draw and opening a few directories for document processing.
Now, using this utility, I can check to see if an application is already
present before loading it so I don't get multiple copies of applications if
I run the desktop boot file again, or want to run another one for doing two
or more things at once.
This utility will only work under RISC OS 3. Under OS2, it'll assume that
the task is not present. This is because it uses calls new to OS3.
How?
~~~~
You have a choice on how to use TaskEnsure. Firstly, you could copy the
TaskEnsure file into your Library directory, or you could load the
TaskEnsurM module. The first option is probably best for hard disc users.
I've provided it as a module and an executable file so that you can make the
choice.
Either way, the effect will be to add another *command to the vast
repertoire your computer already has. The syntax is
TaskEnsure [-p] <task name> <*command>
The task name is the name of the task to check for. Matching is case
sensitive. If the task name includes spaces, enclose the task name in "s.
If the task is not present, the *command is executed. This may include
spaces without quotes... simply, the rest of the line is sent to the CLI.
If the -p options is included (it's position is important), the sense of the
command is reversed, and the command is executed if the task IS present. I
wish RMensure had this facility!
Examples
~~~~~~~~
To load Draw it it's not already present.
TaskEnsure Draw Filer_Run resources:$.Apps.!Draw
To load a printer driver if draw is present.
TaskEnsure -p Draw TaskEnsure "Printer Manager" Filer_Run ADFS::Ben.$
.Document.Printers.!Printers
note: this command should be all on one line.
This last example illustrates three points. Firstly that the -p option is
actually useful, and secondly the 'double' TaskEnsure command. The first
TaskEnsure sees if Draw is present, the second only loads Printers is it is
not already loaded. Thirdly, the task name of Printers has a space in it and
so is enclosed in quotes.

is written in ARM code, and is assembled by the Acorn Assembler (not the
BASIC one).
