The article informs that members of the Association for Computing Machinery's annual national conference are happy with the caliber and quantity of the papers received by them for the conference which will be held on August 24-26, 1965 in Cleveland, Ohio. Two years ago, the intensive technical refereeing process was introduced for screening papers for ACM national conferences. Technical papers will be given importance in the conference for the educational benefit of students. Public relations chairman for the conference Raymond F. Hitti is cooperating with professor Lewis Winner in planning the conference.

The article reports on the fourth symposium of the Association for Computing Machinery, on Operating Systems Principles. For the symposium, over 60 papers were submitted to the program committee in response to a call for papers. From this set, 21 papers were selected for presentation in five formal sessions. Two sessions on the first day of the symposium contained papers describing principles relevant to operating system design and measurement, as well as papers describing complete operating systems. An important focal point of the symposium was the topic of computer security and protection. The banquet speaker, professor Maurice Wilkes of Cambridge University, also emphasized protection. The need to understand the technical aspects of security is particularly urgent in view of the current national attention being given to the social implications of computerized data banks and the rights of citizens. The symposium was co-hosted by the Computer Science Department of Yale University and the Computer Sciences Department of IBM Research Center.

The article analyzes existing and proposed American and foreign standards for one inch perforated paper tape for information interchange. This standard covers the physical dimensions of the paper tape and its perforations. The unpunched tape shall have an overall nominal width of 1,000 inch and shall have a nominal thickness of .004 inch. The tape shall be used for recording up to eight levels of information across the tape. The longitudinal center line of the feed holes shall be parallel with the reference edge of the tape and located .392 inch plus or minus .004 inch from the reference edge. The feed holes in the tape shall be fully punched and round with a diameter of .046 inch plus .002 minus .001 inch. The code holes in the tape shall be fully punched and round with a diameter of .072 inch plus or minus .002 inch. All holes punched in the tape shall nominally center on the true intersection of longitudinal and perpendicular transverse center lines spaced .100 inch apart.

The effective operation of free enterprise in creating the envisioned information service industry is dependent upon three accomplishments: (1) the restructuring of our information processing industry so that a clear division of costs is mode among computing, communications, and the development of information services; (2) the wide use of multiaccess system concepts so that information services may share in the use of computer installations and so that the cost of their construction is reasonable; and (3) the development of public, message-switched communications services so that adequate provisions are made for Information security.

The prize included $150 cash, and for each author a three-year subscription to the ACM serial publication of his choice. Third place was given to the paper "An Extensible Editor for a Small Machine with Disk Storage," by Arthur J. Benjamin of Brandeis University. The prize included $100 cash, and a three-year subscription to the ACM serial publication of his choice. All of the refereeing of Competition papers was done by graduate students at various colleges and universities.

The article presents information on the proposed American Standard, "Eleven-Sixteenths Inch Perforated Paper Tape." This standard covers the physical dimensions of the paper tape and its perforations. This standard is for perforated paper tape with fully punched round holes. The punched tape shall have an overall width of 0.686 inch plus or minus 0.003 inch after the tape has been conditioned to within 69.5 degrees F to 76.5 degrees F and 48 percent to 52 percent relative humidity for a period of 24 hours. The tape shall be used for recording up to five levels of information across the tape. The feed holes in the tape shall be fully punched and round with a diameter of 0.046 inch plus 0.002 minus 0.001 inch. All holes punched in the tape shall nominally center on the true intersection of longitudinal and perpendicular transverse center lines spaced 0.100 inch apart. Tolerances on locations of code holes in any one transverse row, relative to the center lines of the feed hole in that row, shall be plus or minus 0.002 inch in the transverse direction and plus or minus 0.003 inch in the longitudinal direction.

This article focuses on the Association for Computers Machinery (ACM) 1968 National Conference and Exposition that was held during August 27-29, 1968 in Las Vegas, Nevada. A keener recognition of member interest and professional responsibilities characterizes the spirit in which the Conference Program for ACM68 was organized. Appropriately, technical and special sessions of timely and practical concern to the information processing; community have been planned for Conference attendees. The Program Committee has worked with ACM Special Interest Groups (SIG) and Special Interest Committees (SIC) in an effort to integrate SIG/SIC efforts with the aim of presenting a distinguished program. By developing sessions with the cooperation of ACM SIG's and SIC's, the Program Committee has attempted to evolve a program which is most responsive to the needs of the ACM membership. SIG and SIC also assisted the Program Committee by encouraging their members to develop and submit papers, and by advising the SIC on the newest developments in each special interest area. Further, they were able to provide knowledge and guidance to the SIC for the selection of session chairmen and technical paper referees.

This article presents several research papers related to computing machinery and computer programs. Designing a system for the analytic processing of mathematical functions around a central syntax processor and permitting the user to work within the context of mathematical syntax leads to a flexible system with a broad range of capabilities. One advantage of the approach mentioned in "A Syntax-Directed Approach to Automated Aids for Symbolic Math," by L. Clapp, is that the basic system can be developed without many a prior restrictions on the nature of the mathematical entities to be processed. Once the basic structure has been developed, the user is free to define and operate within his own system of mathematics by modifying or extending the syntax definitions. In the paper "Programming Languages, Logic and Cooperative Games," by L. Hodes, an application of computers is presented which is not restricted to a single problem area but is perhaps not general purpose enough to be considered programming language, even a problem-oriented one.
