There has been several replies to this post, but so far no-one has
answer the question. ;-)

YES, it is possible to read specific sectors in SwiftForth. The
easiest way is to read the whole disk at once, with code similar to
this:

1440 1024 * CONSTANT SIZE
SIZE BUFFER: DATA
S" \\.\A:" R/O OPEN-FILE THROW
( fid ) DATA SIZE THIRD READ-FILE THROW SIZE <> THROW
( fid ) CLOSE-FILE THROW

After it runs, you will have the contents of a high-density flopply
in A: stored at DATA.

According to the documentation, you need Windows NT and you must
have administrative privileges.
