2. In Search of the Original Fortran Compiler.

Author

Abstract

In April 2002, Grady Booch sent out an email with the subject "Preserving classic software products." His appeal to provide top 10 lists and to suggest where to look for the source code received an enthusiastic response. Grady and the Computer History Museum organized a workshop in October 2003.1 As a result, a month later, a group of Computer History Museum trustees, staff and volunteers (including me) established the Software Collection Committee2 (SCC) to explore the software side of the museums mission: "To preserve and present for posterity the artifacts and stories of the information age." This article focuses on the collecting of Fortran materials. [ABSTRACT FROM PUBLISHER]

3. A Nonrecursive Method of Syntax Specification.

Author

Abstract

The use of the Kleene regular expression notation for describing algebraic language syntax, in particular of ALGOL is described in this paper. A FORTRAN II computer program for carrying out the elimination algorithm of Gorn, similar to Gaussian elimination for linear systems of algebraic equations, is described. This was applied to numerous smaller languages, including some sublanguages of ALGOL. A hand calculation result of the application of the algorithm to all of ALGOL is given, thus expressing the Revised ALGOL 1960 syntax in completely nonrecursive terms, as far as its context-free portion is concerned. This description in many ways is far more intuitively understood than the previous recursive description, it is suggested. The paper also includes results of the machine program, which does not include a simplification algorithm. [ABSTRACT FROM AUTHOR]

4. Computer analysis of general linear networks using digraphs.

Abstract

The objectives of the work described in this paper were to investigate the application of digraphs in analysing general electronic networks and to develop a computer programme based on a particular digraph method developed by Chen. The Chen digraph method is a topological method for solution of networks and serves as a short cut when hand calculations are required. The advantage offered by this method of analysis is that the results are in symbolic form. It is limited, however, by the size of network that may be handled. Usually hand calculations become too tedious for networks larger than about five nodes, depending on how many elements the network contains. Direct determinant expansion for a 5-node network is a very tedious process also.
The work resulted in a short-cut approach to the formulation of a digraph from a network in the form of a table of digraphs for all network elements. The table is included in this report. The work also resulted in a computer program implemented in FORTRAN II code for the University of Santa Clara IBM 1130 computer with which a given digraph can be analysed. The output of this programme is the determinant and all co-factors of the node admittance matrix. [ABSTRACT FROM AUTHOR]

6. NEGATIVE AND ZERO SUBSCRIPTS IN FORTRAN II PROGRAMMING FOR THE IBM 1620.

Author

Garber, M. J.

Subjects
*SIGNED numbers, *INTEGER programming, *FORTRAN, *FORTRAN II, *IBM 1620 (Computer), *NUMBER concept, *PROGRAMMING languages, *ELECTRONIC data processing, *MATHEMATICAL programming
Abstract

The article presents the impact of subscripts with unsigned integers to FORTRAN II programming. The elimination of attaching sign to integers creates a negative response in terms of summarizing completed questionnaires. The study concerning subscript values using the IBM 1620 in FORMAT FORTRAN and in FORTRAN II provides a conclusion that the requirement of eliminating signs on subscripts is not implemented by programming logic but by the processor. Various examples illustrating negative and zero subscripts in one-way, two-way, and three-way arrays are provided.

7. THE USE OF COBOL SUBROUTINES IN FORTRAN MAIN PROGRAMS.

Author

Tahri, Kazuo

Subjects
*COBOL (Computer program language), *FORTRAN II, *FORTRAN, *COMPUTER programming, *COMPUTER software, *PROGRAMMING languages, *ARTIFICIAL languages, *AUTOSATE, *TECHNOLOGY
Abstract

The article discusses the use of Cobol subroutines in Fortran main programs. The program demonstrate the simple technique of combining two computer program language, Cobol and Fortran. The main program were run on IBM 7090 and written in Fortran and the subroutine Cobol. Some of the advantages of Fortran II Chain System is presented including the immediate availability of a set of chain jobs, thus reducing the tape-handling necessary, setting up of an additional chain or modifying one of the chains without having to recompile the entire chain.

8. Remembering... BASIC.

Author

Hayward, David

Subjects
BASIC (Computer program language), PROGRAMMING languages, FORTRAN II, COMPUTER programming education
Abstract

The article discusses the revival of educational computer programming that forced a change in the curriculum. It refers to the Beginner's All-Purpose Symbolic Instruction Code (BASIC) designed by computer scientists John Kemeny and Thomas Kurtz in 1964 for less technical people working on computers. It states that BASIC was based on programming language Fortran II and other languages to teach students the interactive aspect of mini computers adopted by schools, colleges, and universities.

9. Interactive three-dimensional design and drawing on computer-displays

Author

Encarnacao, J., Hunger, J., and Publica

Subjects
fortran ii, pradis, computer graphics, interactive drawing, computer display, coordinate transformations, ziddi, command language, three dimensional objects, display systems, baukas
Abstract

This paper introduces two programs-ZIDDI and BAUKAS-which enable the user to store a representation of three- dimensional objects by the interactive drawing of two views of the objects on a computer display. ZIDDI allows the user to draw the objects directly as a set of points, lines, etc. in two views using a command language and coordinate transformations (rotation, translation, etc.). BAUKAS permits the construction of very complicated objects as a combination of various primitives, which have previously been drawn using ZIDDI and are then available as commands. Both programs were written in FORTRAN II and are two of the possible input modes of the display programming system PRADIS.
