Prospects of embedding MARK IV in SGS (Simultaneous Graphics System) to establish a usable online file management system. SGS is a small time-sharing system that supports six terminals, designed to provide remote access to an IBM 360 computer using IBM 2260 graphic terminals. The user is provided with a full range of text-editing facilities and has the ability to add, delete, or modify data in a file. In many applications, it is desirable to separate data into different files: JCL statements for one, MARK IV requests for another. To test a MARK IV master file of registration cards and three SGS data files, runs were initiated via the 2260 terminal to catalog the file definitions and prepare a series of reports. Improvements in entering formatted data need to be implemented. Additional storage devices and remote consoles, as well as conversion to a multiprogramming system such as OS/MVT would probably enhance the capabilities of the system.

The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
