I think you can read chunks of 256, 512, 1024 or more:
do
read #file1, s1, -256
read #file2, s2, -256
if s1<>s2 then
files_are_different()
break
endif
while len(s1)=256
Note the "-256" which reads up to 256 bytes, or up to the end of file.
Ideally, the higher the number the quicker should be, but some
experiment should be done. May be 8192, 16384 or so could do well.
I didn't try this, however.
