Character to Real*8
Hi, This hopefully is a basic question. How do I equate a real to a character if I know that the character array contains a number. E.G. real*8 X character a(*) x= real(a(0:10)) doesn't work but what does? Thanks, Rudy ... 13 Jun 2006 13:10

Thanks!
That's a lot of help! I have never explored the 'fanciful' extras in the READ statement, especially the internal files, but now I got it working!

Ada vs Fortran for scientific applications
I like to discuss the technical reasons why Ada is not used as much as Fortran for scientific and number crunching type applications? To make the discussion more focused, let's assume you want to start developing a large scientific application in the domain where Fortran is commonly used. Say you want to d... 6 Jun 2006 04:10

'Fortran' is the word an acronym or a portmanteau?

Pointers and dynamic data structures in Fortran 90/95
Hi, I am an engineer and for my job I need learn how to use pointers and dynamic data structures in Fortran 90/95. I know Fortran 77 and I have a good reference for Fortran 90/95, "Fortran 90/95 for Scientists and Engineers" by Stephen J. Chapman, 2nd ed. 2004. However, my problem is not the language itself, but... 19 May 2006 12:48
