This analysis is not correct - it makes the run time library think this
is an unformatted file.

I asked around on comp.lang.fortran; this is the result:

Fortran 77 left this open - Fortran 90 interpreted it as:  The record
length is the maximum you can use (write to) on sequential I/O.

I made a fix to the g77 run time library to allow RECL=nnn without
having it assuming you want unformatted I/O.

This change will be in the next major release.

Cheers,
