No, unfortunately not.  The size of the record lengths embedded in 
unformatted sequential files (and those used for direct access files) 
just have the size of whatever happens to be `long' on the architecture 
g77 and its run-time library were compiled for.

So on most architectures this is 32 bits, except for Alpha, where it is 
64 bits.

It's not easy to change this in such a way that everyone could still 
read his/her old unformatted sequential files *and* use the larger size 
when necessary.

[ Not easy here means: g77 is in maintenance mode and this can only
   be solved by introducing a compile time option that determines
   the size of the type used for record lengths, which is a pretty
   involved change ]

I'm sorry.
