Yes, that's my plan. 

I've plotted out the relationship between the buffer number of each
line coming in and the print order. Until the point where line buffer
0 gets written for the first time (a scroll) the line from the top of
the screen start from buffer zero. But after first overwrite, the top
line buffer number is always the same as the next buffer to be
written to. I've now got an algorithm for that.

Ah. Thanks for that, I was puzzling over that.

Working on it, but I find 'challenging' and I'm spending hours on it.

I've deliberately not said. 

I've been ripped into in the past for this, so I almost feel ashamed
to say - Basic assembler.

I don't have any logical justification for my choice, I just like it
and understand it more than wordy hi-level stuff. Yes, I know it's
hard to maintain, takes ages to code etc. but it's a hobby for my
retirement.

Steve what a kind offer but I don't wish to burden you. However, when
I get stuck as I'm sure I will, a bit more advice would be
appreciated.

I'm concerned about conversion to and from work area coords which I
think will darken my doorstep a little. :-)

Strangely, I don't feel 'stuck' just at the moment.

Thanks, very much indeed.

Bob.
