Software Support
The Series/1 could be ordered with or without operating system. Available were either of two mutually exclusive operating systems: Event Driven Executive (EDX) or Realtime Programming System (RPS). Systems using EDX were primarily programmed using Event Driven Language (EDL), though high level languages such as FORTRAN IV, PL/I, Pascal and COBOL were also available. EDL delivered output in IBM machine code for System/3 or System/7 and for the System/1 by an emulator. Although the Series/1 is grossly underpowered by today's standards, a robust multi-user operating environment (RPS) was available along with several additional high level languages for the RPS OS. The EDX operating system was originally ported from the System/7.
Systems without operating system were intended for users needing dedicated applications that did not require the full capabilities of either OS. Applications were built using a set of standalone programs, called the Base Program Preparation Facilities, consisting of a macro assembler, a link editor and some basic utilities. A set of modules, called Control Program Support (CPS), was linked with the application to provide task management, data processing input/output support and initial program loading for both disks and diskettes.

Famous quotes containing the word support:
“I make this direct statement to the American people that there is far less chance of the United States getting into war, if we do all we can now to support the nations defending themselves against attack by the Axis than if we acquiesce in their defeat, submit tamely to an Axis victory, and wait our turn to be the object of attack in another war later on.”
—Franklin D. Roosevelt (1882–1945)
