Hi good afternoon.

Where is the screen address of the graphic please?
I want to plot on the screen with poke.

Thanks.

That's not a BBC BASIC question, it's a question about whatever platform you are running your program on. The answer may well be "inaccessible" as the platform your program is running on may well disallow direct access to the screen memory, or it may be impossible to determine or access.

On many platforms that BBC BASIC runs on the "screen memory" is down the other end of an opaque I/O port. Certainly on most PDP11 platforms the "screen memory" is down the other end of a serial link, and it is impossible to know how the display equipment has chosen how to represent the display in its memory. When you run BBC BASIC in a web browser, the "screen memory" is in the *other* *person's* computer's webbrowser.

Why do you want to do it? Just use the normal VDU display APIs.

Hello thanks for the information.
I will then do it via the vdu.

Thanks.
