Abstract: A port of the IRAF system has been done to the new operating system OSF/1 on the DEC 3000/500 machine. The main features of the DEC OSF/1 is a 64-bit kernel architecture based on the Mach V2.5 kernel design with components from BSD 4.3, system V and other sources. These features give flexibility to the user that ports large pieces of software; since OSF/1 is compatible with Berkeley 4.3 and System V programming interfaces. The purpose of these notes is to point out the details in dealing with the port of IRAF in the new 64-bit address space and specially to discuss possible solutions to the SPP programming language 32-bit pointers, and the actual solutions reached in creating the IRAF executables.
