 ROM values via the r register on the
Z80 is more random!)</P>

<H2>A few precautionary notes</H2>

<P>Due to a small feechure in z80asm which causes DEFVARS -1 to be
incorrectly resolved when linking object files, all assembling takes
place at one time, this means that the -a flag is ineffective, and is
equivalent to -c when the -create-app flag is supplied. So, as a result
don't compile to object files then link - you'll trash the lower memory
of the Z88! [Been there, done that!]</P>

<H2>In summary</H2>
