I think you will find it is wanting a disc containing the text to all the
messages etc. in some language other than english.  Take a good look at
your country configuration.

It could meen that you have a duff MEMC but more likely some program has
writen over the soft copy of the CAM map and the task manager does not
know what to do about it.

Thanks for your answers to both of my questions. I have checked the
country configuration, and it is set to UK. No modules are unplugged,
and furthermore, the computer does not appear to look for any files
once a key has been pressed.

Any changes to the version of BASIC that comes with Risc-OS 3.1 over
Risc-OS 2.0?  I don't recall any recent mention of this, though I'm
sure that there are changes, if my memory serves me correctly.

It is not your *country* configuration - it is your *territories* configuration
Look in your welcome/user guide. Your Territory should be set to 1 for UK I
think.
(I did try and email you about this on Saturday Simon - but have had lots of
failure messages from your site ... )

The CAM is the memory in the MEMC chip which is used to look up logical->
physical memory mappings.  Either RISC OS 3.1 is very buggy or you have
a faulty MEMC.  The CAM being corrupt means that the machine is unusable
when that part of memory has been accessed since the memory access will
be mapped to the wrong place.

Is the error happening only when you have a lot of tasks running?

I don't know if there has been an update since v1.05, but this had several
improvements over the 1.04 in RISC OS 2.00. I can't recall most of them,
but I do remember that it gives proper error messages when errors occur
in libraries (i.e. the real library line number is given as ERL instead of
the last line of the main program!), and it also allows
  IF whatever THEN :REM a multi-line if-then statement
    do-something
  ENDIF
while BASIC 1.04 took the first line as being a single-line IF-THEN.
(Actually a bit annoying as it broke several programs of mine that relied
on the fact that I could say:
  IF condition THEN :REM I must write some code here!

There are also some new instructions I think...

If the RISC OS 3.10 basic is unimproved, I'll be incredibly
annoyed. How many people have come across the problem where
*Basic -quit <filename> (ie double-click on a basic program)
doesn't in fact clear the variable space. This has the
delightful result that you can write code that accesses
variables that don't exist. Basic can find them somewhere
(with of course, totally screwy values), and your code will
run with garbage variables, and quite possibly crash (machine
code).

The only way to avoid this is to load and run the program
directly from basic, or to (as we have) set up Alt-click
on basic programs to *Basic -chain <filename>.

Blee.

Yeah, CRUNCH, TEXTLOAD, and TEXTSAVE spring to mind:

{Cranks up a taskwindow}

>HELP CRUNCH
This command removes specified spaces from the current program.
CRUNCH <expression>. The bits in the number mean:
0: spaces before statements
1: spaces in statements
2: REM statements (except first)
3: empty statements
4: empty lines
>
>HELP TEXTLOAD
This command loads a new program, converting from text form if rqd.
>
>HELP TEXTSAVE
This command saves the current program as text [with a LISTO option].
TEXTSAVE[O <expression>,] <string>

I also believe that Basic 1.05 will CRUNCH 31 any program that was started
up with a *Basic -quit command.

    Cheers, Julian.
