Features
The System/38 had 48-bit addressing, which was unique for the time, and a novel database-like storage schema. The operating system of the System/38 was called CPF, for "Control Program Facility" CPF is not related to SSP, the operating system of the IBM System/34 and System/36.
The System/38 also had security built in as part of its architecture. Each object or library could have access controlled on a user-by-user basis. This has been continued and expanded throughout the AS/400 and iSeries computer lines.
Languages supported on the System/38 included RPG III, COBOL, BASIC, and PL/I. The operational control language of the System/38 was called CL, for "Control Language". CL programs, similar in concept to shell scripts, could be compiled and executed natively.
