The Access Method Services utility program IDCAMS is commonly used to manipulate ("delete and define") VSAM data sets. Custom programs can access VSAM datasets through Data Definition (DD) statements in Job Control Language (JCL), via dynamic allocation or in online regions such as in Customer Information Control System (CICS).
A Generation Data Group [10] (GDG) [11] is a group of non-VSAM data sets [12] that are successive generations of historically-related data [13] stored on an IBM mainframe (running OS or DOS/VSE). [14] A GDG is usually cataloged. [13] An individual member of the GDG collection is called a "Generation Data Set."
IDCAMS ("Access Method Services") generates and modifies Virtual Storage Access Method (VSAM) and Non-VSAM datasets. IDCAMS was introduced along with VSAM in OS/VS; the "Access Method" reference derives from the initial "VSAM replaces all other access methods" mindset of OS/VS. IDCAMS probably has the most functionality of all the utility ...
According to two sources, one who strategized with the Mercers and another who worked closely with Trump, Rebekah insisted on a 30-minute face-to-face meeting with Trump, in which she informed him that his campaign was a disaster. (Her family had pledged $2 million to the effort about a month earlier, so she felt comfortable being frank.)
IEFBR14 was created because while DD statements can create or delete files easily, they cannot do so without a program to be run due to a certain peculiarity of the Job Management system, which always requires that the Initiator actually execute a program, even if that program is effectively a null statement.

An IBM System Z10 mainframe computer on which z/OS can run. z/OS is a 64-bit operating system for IBM z/Architecture mainframes, introduced by IBM in October 2000. [2] It derives from and is the successor to OS/390, which in turn was preceded by a string of MVS versions.
Stop-and-copy garbage collection in a Lisp architecture: [1] Memory is divided into working and free memory; new objects are allocated in the former. When it is full (depicted), garbage collection is performed: All data structures still in use are located by pointer tracing and copied into consecutive locations in free memory.
