I'm posting this message on behalf of a co-worker. His company (Union Carbide Corporation) and mine (The Dow Chemical Company) merged about two years ago. He is using Digital Visual Fortran 5.0D and wants to upgrade to CVF 6.6.
UCC apparently had a company-wide license for DVF, and my co-worker loaded the copy he's got from a server. I don't know the details of how this worked. According to the upgrade information at http://h18009.www1.hp.com/fortran/visual/pricing.html he will likely need a DVF license code to purchase the upgrade, but he doesn't have one like the people who purchased individual boxed product.
Can this guy get the discounted upgrade prices listed on the HP/Compaq Web site, and if so, then how should he do it?
