OK, then it's a bug in NONMEM VI. Submit a bug report to the NONMEM VI developers. I cited both the Fortran 77 and Fortran 95 standards, which show that this is nonconforming code. Feel free to send my email to them. You can also tell the NONMEM VI developers that once a unit number is opened, it is global to entire program. Under the Unix idiom, /dev/tty and /dev/null are (special) files. Try 'man 4 null' and 'man 4 tty' on your Redhat box. > Regardless, it's code that runs in an older version that doesn't run > in a new version.

The code never ran with an older version of gfortran unless an older version of gfortran had a bug that permitted it. gfortran and g77 are not the same compiler. While gfortran tries to provide backwards compatibility with g77, the author of g77 made several questionable choices with violating the Fortran 77 Standard. gfortran follows the Standards. Hopefully, "this problem will cause people to" fix their code. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38122
