File Handle

[Mel Bishop]

Can somebody tell exactly what a "file handle" is and how it is
extracted? If I have the following code:

y = freefile
open "somefile.txt" for binary as y
...
...
close #1

Now I know that (y) is not the DOS handle of the file but I need
to know how it is determined so I can use some interrupt 21 calls.
I have looked all over the place but can't seem to find it.

Thanks.

Have you looked under FILEATTR Function, it says File Number is
the handle of a currently open file.

FILEATTR(FileNumber%, 2) returns a file's dos handle.

Make sure that "close #1" is actually "close #y".

Jerry, I never even saw that in the documentation. Thanks.

Tom, old habits die hard. Oops.
