--- Comment #6 from ARuopp <aruopp at gmx dot de> --- Hi, thank you very much for your effort. Compiling is not the problem. Try to execute the script, which I attached. Without the "backspace" modification, xfoil ends with the error message: At line 655 of file ../src/iopol.f (unit = 9, file = 'polarfile_1.dat') Fortran runtime error: Sequential READ or WRITE not allowed after EOF marker, possibly use REWIND or BACKSPACE Is your xfoil running without the modification?
