Fortran / Visual Basic ?? I wrote more then few dosens programs in all flavors of Basics, mostly in DOS. Unfortunatelly with the new Windows systems, 32, 64 bit they are no longer usable. I would like to rewrite some of them. It is mostly structural engineering, cams, linkages. The codes are not that huge, from 120 up to 500 lines. Should I go for Fortran, I have to relearn it, or go with Visual Basic. I would like to compile it as the stand alone and be able to run it on Windows 7 and 8, both 32 and 64 bit systems. Thanks for the advise.
