Sounds like you're mixing apples and oranges, which is fine as long as you've
got a good reason. If you've a file that has a known record length then I'd
stick to RANdom file access. Much easier to handle. If, however you're
attempting to, say, copy the file then the record length makes no difference
so don't worry about it....
 
OPEN "B", #1, FileName$
BytesLeft& = LOF(1)
WHILE BytesLeft& > 0
  Chunk% = MIN(32000,BytesLeft&)
  DECR BytesLeft&, Chunk%
  GET$ #1, Chunk%, A$
  ' ... do what you want with a$ here
WEND
 
This will get a fresh 32000 bytes and stuff them into A$ until you hit the 
nd
of the file as long as you do not access the file from anywhere else for any
other purpose. If you must do that then you'll have to keep track of where in
the file you got the last chunk from.
