The program is very old and this is clearly visible from the code (well written, but in old Fortran, coping with severe limitations of memory) and from the input and output formats. However, Maxwell’s laws have not changed and the program has been tested and validated over more than 40 years. This outweighs most if not all of the inconveniences (in my personal view),.
