Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hello all,
One of the many great aspects of the LCD screens on the MM170 etc is that one can stop the program (^C) and the screen is retained so you can then interactively test graphics via the console.
Can one do this on the CMM2? As far as I can tell - NO, not easily.

In Peter's first graphics tutorial he shows how you can draw a line over the text on a screen. But I am talking about complex graphics that you would not do via the console.

One option is to SAVE IMAGE from within the program, then, from the console, LOAD the image and then test your graphics - this works but is a bit clumsy.

Are there any better ways?
Or, can an image be held stationary like a PC Desktop?

Cheers,

Andrew

create the image on a page other than zero. Then when back at the command prompt execute PAGE COPY to restore the image
