2. IBM Basic assembly language and successors - Wikipedia

   en.wikipedia.org/wiki/IBM_Basic_assembly...

   The application program interfaces of IBM's mainframe operating systems is defined as a set of assembly language "macro" instructions, that typically invoke Supervisor Call (SVC) [e.g., on z/OS] or Diagnose (DIAG) [on, e.g., z/VM] instructions to invoke operating system routines. It is possible to use operating system services from programs ...

   en.wikipedia.org/wiki/Support_programs_for_OS/...

   Extracted from IBM manual SC26-7414-08 z/OS DFSMSdfp Utilities: The IEBISAM program is no longer distributed. Starting in z/OS V1R7, ISAM data sets can no longer be processed (created, opened, copied or dumped). ISAM data sets that are still in use must be converted to VSAM key-sequenced data sets.

4. IBM mainframe - Wikipedia

   en.wikipedia.org/wiki/IBM_mainframe

   The primary operating systems in use on current IBM mainframes include z/OS (which followed MVS/ESA and OS/390 in the OS/360 lineage), z/VM (which followed VM/ESA and VM/XA SP in the CP-40 lineage), z/VSE (which is in the DOS/360 lineage), z/TPF (a successor of Transaction Processing Facility in the Airlines Control Program lineage), and Linux ...

   en.wikipedia.org/wiki/IBM_System/390

   The IBM System/390 is a discontinued mainframe product family implementing ESA/390, the fifth generation of the System/360 instruction set architecture.The first computers to use the ESA/390 were the Enterprise System/9000 (ES/9000) family, which were introduced in 1990.

6. z/Architecture - Wikipedia

   en.wikipedia.org/wiki/Z/Architecture

   IBM's operating systems z/OS, z/VSE, z/TPF, and z/VM are versions of MVS, VSE, Transaction Processing Facility (TPF), and VM that support z/Architecture. Older versions of z/OS, z/VSE, and z/VM continued to support 32-bit systems; z/OS version 1.6 and later, z/VSE Version 4 and later, and z/VM Version 5 and later require z/Architecture.

7. IBM Z - Wikipedia

   en.wikipedia.org/wiki/IBM_Z

   A pair of IBM mainframes. On the left is the IBM z13 (while the naming was changed, the z13 line had a zSystems label on doors). On the right is the IBM LinuxONE Rockhopper. IBM Z [1] is a family name used by IBM for all of its z/Architecture mainframe computers.

8. PC-based IBM mainframe-compatible systems - Wikipedia

   en.wikipedia.org/wiki/PC-based_IBM_mainframe...

   IBM had demonstrated use of a mainframe instruction set in their first desktop computer—the IBM 5100, released in 1975.This product used microcode to execute many of the System/370's processor instructions, so that it could run a slightly modified version of IBM's APL mainframe program interpreter.

9. History of IBM mainframe operating systems - Wikipedia

   en.wikipedia.org/wiki/History_of_IBM_mainframe...

   The history of IBM mainframe operating systems is significant within the history of mainframe operating systems, because of IBM's long-standing position as the world's largest hardware supplier of mainframe computers. IBM mainframes run operating systems supplied by IBM and by third parties. The operating systems on early IBM mainframes have ...
