If you are working on scientific calculation, you must know FORTRAN. Hence you will meet a lot of
I JUST HATE IT.
GOTO looks like interchange. Well, it is good for crossroad. But frankly speaking, I do not know how to drive :-(.
I read blogs saying that, if you are a new guy in a group, DO NOT REFACTORING THE OLD UGLY FORTRAN CODES. Although I am not new here, I prefer let the code be as it was. However, some guys should know that FORTRAN is not popular any more in certain situations and I think it time that we should try to use more elegant languages, like the new C++(well, too complicated) or python(but I dislike it).
There is a webpage which told us how to do 'modernization' to your old FORTRAN code. I will read it carefully and try it.
