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?
