Indeed; the record length in bytes.

Nope.

The reason this is done this way is to be able to support several 
Standard Fortran I/O requirements on an OS that doesn't have a native 
record structured file format:

1. Skipping an unformatted record via an "empty" read:

       READ(7)

2. Backspacing an unformatted record:

       BACKSPACE(7)

Sorry to be of so little help.
