--- Comment #4 from patnel97269-gfortran at yahoo dot fr --- Ok so if I understand well, for gfortran once the input_unit is closed, the unit number corresponding to input_unit can be used for another file. But, the input_unit is defined to be the standard input. 1) If one wants to reconnect to standard input socket (/dev or /proc) how to find out with gfortran without knowing the file path ? 2) it is allowed to change some properties of an already connected unit by calling the open function again without closing first. When i do so , using open(unit=input_unit,status='old' ,access='stream') inquire(unit=input_unit,name=nm) print *,nm inquire(unit=input_unit,size=sz) I get : At line 26 of file test2.f90 (unit = 5, file = 'stdin') Fortran runtime error: Cannot change ACCESS parameter in OPEN statement And if I just ask the name of the file associated file input_unit with gfortran i get "stdin", with ifort i get "/proc/28683/fd/0". 3) Ifort is automatically reconnecting input_unit to standard input when file is omitted, how is that a bug ?
