This paper reports the results of two studies of the readability of FORTRAN programs, i.e., the ease with which a programmer can read and analyze programs already written, particularly in the processes of maintenance and debugging. In the first study, low-level characteristics of 202 FORTRAN programs stored on the general-use UNIX systems at Bell…

This is a progress report on a project attempting to design a system of compacting text for storage appropriate to disc oriented demand searching. After noting a number of previously designed methods of compression, it offers a tentative solution which couples a dictionary of most frequent character-strings with a set of variable-length codes. The…

Presents a detailed analysis of courseware design activities based upon the use of conceptual data models for content elaboration. Highlights include discussions of computerized training systems, authoring languages and authoring systems, and the distinction between processing and data. (Author/LRW)

Describes an investigation undertaken to indicate the curricular content (knowledge and skills) needed to prepare the accounting student to audit computerized accounting systems. Areas studied included programing languages, data processing, desired course training, and computer audit techniques. (CT)

VOCAL (Voice Oriented Curriculum Author Language) is designed to facilitate the authoring of computer assisted curricula which incorporate highly interactive audio and text presentations. Lessons written in VOCAL are intended to be patterned after the style of informal classroom lectures. VOCAL contains features that allow the author to specify…

With emphasis on currently operating and planned systems that assist users in accessing available network services, this report identifies the techniques used in network access devices. By examining these devices, the trend toward improving the interface between the user and the computer is brought more clearly into focus and up to date. One…

Difficulties in implementing the EXCHECK/VOCAL System, a general program for mathematics instruction written in the VOCAL language, are presented in terms of informal mathematics procedures, audio and prosodic features, and proposed research. References are appended. (CMV)

In order to attain a better understanding of the data processing manpower needs of business and industry, a survey instrument was designed and mailed to 570 known and possible computer installations in the Minnesota/North Dakota area. The survey was conducted during the spring of 1975, and concentrated on the kinds of equipment and computer…

The goal of this project was to find ways of enhancing the efficiency of searching machine readable data bases. Ways are sought to transfer to the computer some of the tasks that are normally performed by the user, i.e., to further automate information retrieval. Four experiments were conducted to test the feasibility of a sequential processing…

The VARAN (variance Analysis) program is an addition to a series of computer programs for multivariate analysis of variance. The development of VARAN exploits the full linear model. Analysis of variance, univariate and multivariate, is the program's main target. Correlation analysis of all types is available with printout in the vernacular of…

To give those business and vocational educators involved in curriculum development a better understanding of data processing personnel requirements, a study was initiated to determine the status of data processing equipment and personnel in selected Pennsylvania businesses. Following a literature review, a questionnaire was developed, revised, and…
