The operation of SORT is directed by control statements, which are largely compatible among various IBM and third-party sort programs. The SORT or MERGE statement defines the sort keys— the fields on which the data is to be sorted or merged. This statement identifies the position, length, and data type of each key.
Job Control Language (JCL) is a scripting language used on IBM mainframe operating systems to instruct the system on how to run a batch job or start a subsystem. [1] The purpose of JCL is to say which programs to run, using which files or devices [2] for input or output, and at times to also indicate under what conditions to skip a step.
IBM Data Facility Sort (DFSORT) Release 10.0; In addition to replacing part of the device support in the base MVS/SP, DFP replaces the Linkage Editor and several utility programs and service aids. DFP is no longer available as a separate product, but has become part of Data Facility Storage Management Subsystem, under the name DFSMSdfp.
For example, TSO on z/OS systems uses CLIST or Rexx as command languages along with JCL for batch work. On other systems these may be the same. On other systems these may be the same. The Non-IBM JCL of what at one time was known as the BUNCH (Burroughs, Univac/Unisys, NCR, Control Data, Honeywell), except for Unisys , are part of the BANG [ 3 ...
Virtual Storage Access Method (VSAM) [1] is an IBM direct-access storage device (DASD) file storage access method, first used in the OS/VS1, OS/VS2 Release 1 (SVS) and Release 2 (MVS) operating systems, later used throughout the Multiple Virtual Storage (MVS) architecture and now in z/OS.
Data Set List – which allows the user to list and manipulate (copy, move, rename, print, catalog, delete, etc.) files (termed "data sets" in the z/OS environment). Member List – for similar manipulations of members of PDSs. Search facilities for finding modules or text within members or data sets.
IEFBR14 consisted initially of a single instruction a "Branch to Register" 14. The mnemonic used in the IBM Assembler was BR and hence the name: IEF BR 14.BR 14 is identically equivalent to BCR 15,14 (Branch Always [ mask = 15 = always ] to the address contained in general purpose register 14).
The SDSF Primary option menu. The System Display and Search Facility (SDSF) is a component of IBM's mainframe operating system, z/OS, which allows users and administrators to view and control various aspects of the mainframe's operation and system resources using an interactive user interface.
