Well, so that is a non-Standard add-on to F77/F95. I've found it in Visual Fortran (the link you sent) and in Open Watcom Fortran (it's manual marks it as non-standard, too). Yet, the gfortran compiler seems to treat the $-fin format the same way like an: ADVANCE="NO" Parameter to a WRITE statement. This implementation seems confusing to me. For that it seems to work, as long as the input fits to a single FORMAT expression.
