Is it actually possible to save the contents of the screen to a memblock?

I know of the save bitmap command, but that causes everything to stop for about 2 seconds while it actually does that, whereas it can seem to write 10000 lines to a file without syncing, and not have any visible on performance

(and then have a section in the menus to convert the memblock back to a normal bitmap... I know I could download fraps, but if possible, I'm trying to require as few external apps as possible...

Thanks in advance, even if it's just not possible...

...maybe one day I'll finish a project

Yes it is,
MAKE MEMBLOCK FROM BITMAP memblock no,bitmap no
Since zero for a bitmap is the screen
MAKE MEMBLOCK FROM BITMAP 1,0 will copy the screen to memblock no 1

To reverse it, MAKE BITMAP FROM MEMBLOCK 0,1

The code above is faster - but still a little slow...

Screen (as a jpeg) to memblock?

(Have I hit a dead end with this idea?)

I've never seen save image and get image before...
I should spend more time in the help page

Sorry if I've wasted your time on such obvious questions...

well save image is pretty obvious what it does
get image grabs a part of a bitmap (in this case bitmap 0),

get image img no. from here x,from here y, to here x, to here y

if you know what i mean, i suck at explaining things

I know WHAT it does - I've just never known the command even existed until I read your post...
