YES! Thanks so much, I've made quite a bit of progress thanks to your help.  In
doing so has raised two more questions.
1. Do you know how to customise the prompt, the bit I've circled here:
http://beebs.ddns.net/images/sync/Prompt.jpg (not sure if it's actually called
prompt, as it uses characters that Mode 7 does not support. I just want to swap
out the divide symbol for something else (I'm at peace with the arrows).
2. When using strings (some that are buffered with "..." like the strings used
for message sender, date etc. are fine, but others will insert a chacter rather
than overwrite a charater like the toggles here
(http://beebs.ddns.net/images/sync/strings.png), did you find a way around
this?
Thanks again, you've been a great help
