Thanks..Actually there are some FORTRAN gurus(Doing research in Physics and Not CS) here who really do not want to learn perl apart form managing files etc.. which they find difficult to do in fort ran and very easy(this is not doubtable at all!!) in perl.. So they want to use similar stuff..for speed for bigger programmes it's expected that this perl to fortran code may/will help..Since they are not directly in CS field we can not expect them to learn perl to the extent they know FORTRAN.. That was the sole reason for this posting.. Regards:-vnpandey
