Software conversion

Writing transportable code is always desireable. Using extensions and enhancements implemented by the manufacturer does not help portability, nor does the use of specific system calls unique to that particular environment.The goal of this article is to show the converse implementation described by Herbert Mayer[1]. The transportation problems are somewhat similar but are also caused by differing implementations of the language --- FORTRAN 77.The two versions described are PRIME FORTRAN 77 (the host language running on a PRIME 750) and Microsoft MS-FORTRAN 77 version 3.1 (and later version 3.2) for the target machine, IBM PC.
