https://community.intel.com/t5/Software-Archive/Run-time-difference-NT-4-Win2K/m-p/934182#M15473 I have a Fortran program that has worked for years under NT 3/4. I recently moved to Win2K. After recompile/link, I get errors such as floating invalid that I never had before. If I bring over the pristine executable currently in production (compiled under NT4) and run it on Win2K, I get the same errors. If I put my Win2K-compiled executable on NT4, it works perfectly. Any ideas? <BR /> <BR />Thanks, <BR />Richard Wed, 10 Jan 2001 00:54:08 GMT Deleted_U_Intel 2001-01-10T00:54:08Z https://community.intel.com/t5/Software-Archive/Run-time-difference-NT-4-Win2K/m-p/934182#M15473 I have a Fortran program that has worked for years under NT 3/4.
