I looking for the means to place a bitmap [b] on top of another BMP [a],
and when I'm finished with [b] it should be cleared of the screen,
leaving only the original [a] bitmap.

The means to do this, seems to be page flipping, but I can't seem to
find any information about it.

I've done a test with the use different screen names when using the blit
command:

Blit(a,screen,0,0,0,0,a->w,a->h);
readkey();
blit(b,screen2,0,0,0,0,b->,b->h);
readkey();
clear(screen2);

It was a shot in the dark, and it didn't work, as screen2 was
undeclared, and I don't know how to declare it.

Could anyone give me a clue to where I could find information on page
flipping?

Thanks in advance.
Einar.
