System Support Program
''System Support Program (SSP)'' was the operating system of the IBM System/34 and System/36 minicomputers. SSP was a command-based operating system released in 1977. ''SSP'' originally contained 60 or so commands that were implemented on the System/34 from 1977 to 1983 in different versions called ''releases.'' History SSP originally contained 60 or so commands that were implemented on the System/34 from 1977 to 1983 in different versions called releases. Release 1 was issued with the original S/34 in 1977. Release 9 was issued in 1981. In 1983, IBM repackaged SSP on a new computer called the IBM System/36, which was not object-code compatible with the S/34. In 1994, IBM repackaged SSP on an updated model of the S/36 called the Advanced/36. The A/36 was an IBM AS/400 which had the SSP implemented as a "virtual machine". Major releases of SSP include: * S/34 ** S/34 Release 1.0 – this was apparently shipped with the first S/34 in 1977. ** S/34 Release 8.0 – this seems to ...

System/34
The IBM System/34 was an IBM midrange computer introduced in 1977. It was withdrawn from marketing in February 1985. It was a multi-user, multi-tasking successor to the single-user System/32. It included two processors, one based on the System/32 and the second based on the System/3. Like the System/32 and the System/3, the System/34 was primarily programmed in the RPG II language. Hardware The 5340 System Unit contained the processing unit, the disk storage and the diskette drive. It had several access doors on both sides. Inside, were swing-out assemblies where the circuit boards and memory cards were mounted. It weighed and used 220V power. The IBM 5250 series of terminals were the primary interface to the System/34. Processors S/34s had two processors, the Control Storage Processor (CSP), and the Main Storage Processor (MSP). The MSP was the workhorse, based on System/3 architecture; it performed the instructions in the computer programs. The CSP was the governor, a diff ...

Screen Design Aid
Screen Design Aid (SDA) is a utility for the IBM System/34 and System/36 midrange computers. Programmers can use SDA to create menus, display formats, or WSU skeleton programs. The System/38, and IBM i platforms also have a utility Screen Design Aid, but its syntax and functionality are different. S/34 and S/36 applications usually involve the operator to a critical degree, whether accepting the bulk of input through display stations or controlling them. Computer programs may utilize unformatted or formatted input, and this is where SDA applies. Creating display formats or menus from code Like RPG II, display formats are built from column-sensitive specifications which describe fields of fixed sizes with fixed or conditioned properties. The System/36 version of SDA gained the H specification, which describes the displays used when the operator presses the "Help" key. The "Help" key can summon one display, a series of displays, or open an online document created by DisplayWri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Control Program Facility
Control Program Facility (CPF) is the operating system of the IBM System/38. CPF represented an independendent line of development at IBM Rochester, and was unrelated to the earlier and more widely used System Support Program operating system. CPF evolved into the OS/400 operating system, which was originally known as XPF (Extended CPF). While CPF is considered to be the operating system of the System/38, much of the hardware and resource management of the platform is implemented in the System/38's Horizontal and Vertical Microcode. Description of the libraries * QGPL – general purpose library * QSYS – system library * QSPL – spooling library * QTEMP – temporary library * QSRV – system service library * QRECOVERY – system recovery library Data storage In most computers prior to the System/38, and most modern ones, data stored on disk was stored in separate logical files. When data was added to a file it was written in the sector dedicated to this, or if the sector w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
System/38
The System/38 is a discontinued minicomputer and midrange computer manufactured and sold by IBM. The system was announced in 1978. The System/38 has 48-bit addressing, which was unique for the time, and a novel integrated database system. It was oriented toward a multi-user system environment. At the time, the typical system handled from a dozen to several dozen terminals. Although the System/38 failed to displace the systems it was intended to replace, its architecture served as the basis of the much more successful IBM AS/400. History The System/38 was introduced on October 24, 1978 and delivered in 1980. Developed under the code-name "Pacific", it was made commercially available in August 1979. The system offered a number of innovative features, and was designed by a number of engineers including Frank Soltis and Glenn Henry. The architecture shared many similarities with the design of the failed IBM Future Systems project, including the single-level store, the use of micro ...

System/3
The IBM System/3 was an IBM midrange computer introduced in 1969, and marketed until 1985. It was produced by IBM Rochester in Minnesota as a low-end business computer aimed at smaller organizations that still used IBM 1400 series computers or unit record equipment. The first member of what IBM refers to as their "midrange" line, it also introduced the RPG II programming language. It is the first ancestor in the product line whose current version is the IBM i series and includes the highly successful AS/400. History At its launch in 1969 it was available for $1000/month — less than half cost of an IBM System/360 Model 20; the smallest member of the IBM System/360 family. Many of the original System/3 model 10 units were shipped diskless, with only the new IBM 5424 Multifunction Card Unit (MFCU) which read, punched, printed on and sorted the new, smaller 96-column punched cards introduced at the same time. IBM delivered the following models: * 1969 — IBM 5410, or System/3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CICS
IBM CICS (Customer Information Control System) is a family of mixed-language application servers that provide online transaction management and connectivity for applications on IBM mainframe systems under z/OS and z/VSE. CICS family products are designed as middleware and support rapid, high-volume online transaction processing. A CICS ''transaction'' is a unit of processing initiated by a single request that may affect one or more objects. This processing is usually interactive (screen-oriented), but background transactions are possible. CICS Transaction Server (CICS TS) sits at the head of the CICS family and provides services that extend or replace the functions of the operating system. These services can be more efficient than the generalized operating system services and also simpler for programmers to use, particularly with respect to communication with diverse terminal devices. Applications developed for CICS may be written in a variety of programming languages and us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distributed Data Management Architecture
Distributed Data Management Architecture (DDM) is IBM's open, published software architecture for creating, managing and accessing data on a remote computer. DDM was initially designed to support record-oriented files; it was extended to support hierarchical directories, stream-oriented files, queues, and system command processing; it was further extended to be the base of IBM's Distributed Relational Database Architecture (DRDA); and finally, it was extended to support data description and conversion. Defined in the period from 1980 to 1993, DDM specifies necessary components, messages, and protocols, all based on the principles of object-orientation. DDM is not, in itself, a piece of software; the implementation of DDM takes the form of client and server products. As an open architecture, products can implement subsets of DDM architecture and products can extend DDM to meet additional requirements. Taken together, DDM products implement a distributed file system. Distribu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetic Stripe Card
The term digital card can refer to a physical item, such as a memory card on a camera, or, increasingly since 2017, to the digital content hosted as a virtual card or cloud card, as a digital virtual representation of a physical card. They share a common purpose: Identity Management, Credit card, or Debit card. A non-physical digital card, unlike a Magnetic stripe card can can emulate (imitate) any kind of card. Other common uses include loyalty card and health insurance card; physical driver's license and Social Security card are still mandated by some government agencies. A smartphone or smartwatch can store content from the card issuer; discount offers and news updates can be transmitted wirelessly, via Internet These virtual cards are used in very high volumes by the mass transit sector, replacing paper based tickets and earlier MagStrip cards. History Magnetic recording on steel tape and wire was invented by Valdemar Poulsen in Denmark around 1900 for recording au ...

Computer Security
Computer security, cybersecurity (cyber security), or information technology security (IT security) is the protection of computer systems and networks from attack by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide. The field has become of significance due to the expanded reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity is one of the most significant challenges of the contemporary world, due to both the complexity of information systems and the societies they support. Security is of especially high importance for systems that govern large-scale systems with far-reaching physical effects, such as power distribution, ...

IBM Office/36
Office/36 was a suite of applications marketed by IBM from 1983 to 2000 for the IBM System/36 family of midrange computers. IBM announced its System/36 Office Automation (OA) strategy in 1985. Office/36 could be purchased in its entirety, or piecemeal. Components of Office/36 include: * IDDU/36, the Interactive Data Definition Utility. * Query/36, the Query utility. * DisplayWrite/36, a word processing program. * Personal Services/36, a calendaring system and an office messaging utility. Query/36 was not quite the same as SQL, but it had some similarities, especially the ability to very rapidly create a displayed recordset from a disk file. Note that SQL, also an IBM development, had not been standardized prior to 1986. DisplayWrite/36, in the same category as Microsoft Word Microsoft Word is a word processing software developed by Microsoft. It was first released on October 25, 1983, under the name ''Multi-Tool Word'' for Xenix systems. Subsequent versions were later ...

MAPICS
Infor XA is commercial ERP software used to control the operations of manufacturing companies. Its prior name, MAPICS, is an acronym for Manufacturing, Accounting and Production Information Control Systems. MAPICS was created by IBM, International Business Machines, but the product is now owned by Infor Global Solutions. Originally all MAPICS code ran only on IBM midrange systems like the IBM System 34, 36, 38 and the IBM AS/400, via succeeding versions of the platform - currently IBM i on IBM Power Systems. Early versions were written in IBM RPG, augmented with Control Language programs. IBM's version of SQL is also utilized on the OS integrated database system called Db2 for i . Recent development efforts have added object oriented components written in the Java programming language, which extends a portion of the XA product to servers running Java. However, the Infor XA product still requires the IBM i operating system. The Java components provide an application run ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Programmer And Operator Productivity Aid
Programmer and Operator Productivity Aid (POP) is an application package written originally for the IBM System/34, which became much more popular and functional on the IBM System/36 and universal on the Advanced/36. POP comprises four major tools: *FILE, which provides easy access to disk files; *LIBR, which provides easy access to libraries and library members; *DISKETTE, which provides easy access to diskette files; *FSEDIT, which is a full-screen text editor in the fashion of the System/38 and IBM i IBM i (the ''i'' standing for ''integrated'') is an operating system developed by IBM for IBM Power Systems. It was originally released in 1988 as OS/400, as the sole operating system of the IBM AS/400 line of systems. It was renamed to i5/OS in ... text editors. POP does not have a function for folders. The Office/36 TEXTFLDR procedure is adequate for this function. POP programs use a point-and-shoot interface. Many objects are displayed and to the left of each object is an ...
