No. I compiled your source code in SAS/C (after changing to ANSI C, C++ has
too many errors) and I recived two MuGA hits.

Change line:
RectFill(gaRP,0,0,SCREENWIDTH,SCREENHEIGHT);
to
RectFill(gaRP,0,0,SCREENWIDTH-1,SCREENHEIGHT-1);
or to... nothing (bitmap was cleared by BltClear() couple lines above!)...
and everything will be fine. Your program rendered outside a screen bitmap...
I really would like see that you will use modern double buffering methods ;).
You have A500 with AmigaOS v1.3 or similar? ;)
