WebAug 7, 2024 · gfortran handles the case of RECL= given in OPEN correctly by returning that value and it handles stream access by using -1. (As the argument becomes undefined, any value would do.) Additionally, gfortran always returns -1 for sequential access instead of returning the default value. The question is only how to handle sequential access. http://hydro.iis.u-tokyo.ac.jp/~akira/page/Fortran/contents/io/general/access.html cowboy riding a tornado
