[BBC-Micro] Scrolling scrolling scrolling...

[Ian Wolstenholme]

You can do this on a Master 128 by using *CONFIGURE
NOSCROLL.

Then the following will work without the screen moving
up a line:

10 MODE 1
20 PRINT TAB(39,31)"*";
30 PRINTTAB(0,0)

Line 30 is required to move to text cursor away from
the last point on the screen otherwise you will get a
scroll up one line when the BASIC prompt comes back.

I'm not sure how you would do this on a BBC B, I don't
think there is a way to turn off scrolling.

Best wishes,


Ian

I'd like to know how to print a character at position (39,31) in MODE 1 _WITHOUT_ the screen scrolling or using VDU 5. I'm sure it must be possible! I remember writing lots of games at scholl none of which used line 31! What a waste

Cheers
