This paper is intended as an outline of the various conventions which are being considered for the use of flowchart symbols in the preparation of all types of flowcharts for information processing systems. The conventions are applied to the use of the symbols appearing in the proposed American Standard Flowchart Symbols for Information Processing Systems. This paper is concerned with the use of the proposed American Standard Flowchart Symbols and not with the symbols per se.

Determining a computing center environment
An investigation is described in which several generally unavailable parameters descriptive of a computing center environment are obtained. The actual data collection and reduction is described, and the results of one month of this collection are tabulated and summarized.
The organization of structured files
A data file is an integral part of a data processing system. In many systems, the selection of an organization for the data within the file can be critical to the system's operating efficiency.
This paper provides the systems designer with an information source which describes ten techniques that may be employed for organizing structured data.
The characteristics of the organizations described are application independent, thus providing the designer with a reference which allows him to limit the number of file organizations he must consider for his system.
Shape the Future of Computing
ACM encourages its members to take a direct hand in shaping the future of the association. There are more ways than ever to get involved.
Get InvolvedCommunications of the ACM (CACM) is now a fully Open Access publication.
By opening CACM to the world, we hope to increase engagement among the broader computer science community and encourage non-members to discover the rich resources ACM has to offer.
