When my PC was transitioned to a Windows-7 one from XP (beyond my control), the Compaq 6.x (I believe) I have been using for years, almost exclusively in the command line mode for f77 type compiles, stopped working. Fortunately, with the original discs from the compiler purchase I found a path to essentially have the appropriate 64-bit-compatible software loaded as necessary and things jumped back to normal. As I frequently distribute the executables produced on this PC to other remote PC users, how concerned do I need to be as to exactly what flavor of Windows the recipient is using regarding whether the code will run at all/properly? Thanks.
