While experimenting with the Exec statement on
the 92+, I have noticed noise appear on the
screen.  Has anybody else seen this?

I have noticed that it doesn't occur in the
same place every time, but it will be
consistant if you try several times in a row.
The more opcodes I pass through Exec, the
more noise I see.  (Sometimes the noise
is erased after the statement is finished,
as the Home Screen redraws, but using a
Pause statement after the Exec will let
me get a chance to see the noise.  Also
I have noticed that the noise is consistant
with certain opcodes; that is to say,
the same opcodes produce the same noise
every time.

If anybody has any ideas why this is happening,
I'd like to know.

Thanks,
