I tried something like this last summer in Fortran and finally gave
up. Fortran really wants to see CR/LF record terminators on its
input. I ended up writing a piece of C code to do it (this type
of i/o is one place C excells). The closest I got to making it
work in Fortran was to declare a long character variable and read
into that. However, you are limited by the length of this variable,
if it works at all.

Good luck!
