Thanks Ackbeet! Defining a new array solved the problem. You're right, in that way I am not overwriting the old array. I appreciate your help! Regards, Abedin

Hi Ackbeet, Thank you for the link! If I wanted to pass all the elements by values then I'd use : call sub(n, arr(1:10)) But either way, it prints the logarithms after the "call" statement rather than the original array.

Hi guys, I am kind of a newbie to fortran and I'd like to ask a simple question. In the code below, I have a main program with one subroutine. It's a simple one. In the main code I am filling an array with elements from 1 to 10. Then I am passing this array to a subroutine "sub", where...

Thanks Chet, Those very nice examples. I will think on them a bit more carefully!

Thanks Chestermiller! I appreciate your help! I solved the problem using your second suggestion, via Moment. Conser. Law and Energy Conserv. Law. However, the first method is kind of obscured to me. I would imagine as the train is approaching at +50 m/s and the ball is flying at a -30 m/s...

Hi guys, I've been thinking on a problem for a while which really bothers me. I've been trying to mathematically solve the following problem: A train approaches the station at a velocity of V=50 m/s. Then a tennis ball is thrown with a velocity U=30 m/s, against the approaching train...

Thank you SteamKing. I've got the program working after checking the EXTERNAL statement, as you had suggested. Thanks again

Hi all, It is my first time to resort to the help of members of this forum :) My question is related to programming in fortran but I am rather new with it. So here is the question:Can I use user defined functions as arguments of a user defined functions in Fortran? I have written a simple...
