Help!  I'm trying to write a program that scrolls a text message
across the bottom of a 4 bitplane hires-interlaced screen, and what
I have been able to do is MUCH too slow!  I am using ScrollRaster()
of the graphics.library...  I rewrote the C program in assembly to
see if it would increase the speed much, and it didn't at all (I was
still calling ScrollRaster() from the asm program).

So, is there a faster way of scrolling a 30-pixel high horizontal
strip of the screen?  Any help would be GREATLY appreciated, even
just pointers to where I can get example source code...

Thanks in advance...

Michael
