Are you thinking of the "filemode" variable? If you set it to 0, "reset"
will open the file in read-only mode, allowing you to open it several
times. Otherwise, if you use reset on a typed or untiped file, it will be
opened in read-write mode and only one process at a time can have a file
opened in this mode.
