A Graphic Capability for MARK IV

B. Casali, Doron J. Cohen

ResearchPublished 1969

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.
