No it's not the disk  - it doesn't get that far - (although the disks and
even the drive may be defective as I haven't been able to try them ) It's
the program I'm having a problem with (my fault).
After copying it from Beebmaster's site, it won't run as I have obviously
copied something down wrongly and I just can't see it despite hours of
checking..
Line 360 is the error trap for the program so it only runs part of the way.
It's the value (in the program) that should be 0 but when I type "PRINT
osblock?12" it gives me a value (not an error code) of 18 which means I have
entered something wrongly.
I'll start from scratch and retype it all again and see what happens. I
haven't got a printer for the Beeb (can't get the ribbons for my old one) so
it's screen to screen checking (cross-eye time).
I suppose this is half the fun of the Beeb anyway.
