Two operating systems available to control the Digital Equipment Corporation (DEC) VAX-11/780 computer were compared. The two operating systems were the VAX/VMS system from DEC and the UNIX system from AT and T. The purpose of the comparison was to select an operating system. The objectives of the study focus on the Fortran environment of each system. The following features are discussed: learning the systems (off-line documentation, on-line documentation, tutorials, mail), basic system elements (the file systems, the command languages), text manipulation (text management, editing, listings, text processing), Fortran language support (the Fortran compilers, the linking loaders, user libraries, Fortran preprocessors), program execution (run-time error messages, input and output, symbolic debugging systems), and execution speed statistics. 4 tables.
