I have written a program in basic, with machine language routines poked in, to
check all the differences on a dos 3.3 disk.  I did this to try to save an
adventure character, noting the changes before and after death.  I initial
used peek(x) and peek(x+4096) to compare two tracks, but this was slow (1 
for 34 tracks).  I then checked my IIe reference books, and found the monitor
Verify routine at $FE36.  From the instructions, it only prints anything wh
it finds a difference, but when I run my program, no matter where the buffer for
the information is (within both hi-res pages) I get the output:

XFCA: GG (GG)

            where X is the page number and GG is a hex digit.  This is in the
correct format, but since they are equal, they should not be displayed!  The
actual value of GG varies, and I think that it is the read in value, But 
still shouldn't be printed!  Any ideas as to what is wrong, or what I'm doing
wrong\??
     Thanks,           Andrew Rahme
