COBOL is an acronym which stands for Common Business Oriented Language. Structure of COBOL Program. Program Divisions Sections – Block of code made up of one more paragraphs. Paragraphs – Block of code made up of one or more sentences. Sentences – Consists of one or more statements and is terminated by full stop. Statements – Consists of COBOL verb and an operand or operands. Words – Reserved, User Defined, Literals, Data Names. There are four divisions in COBOL: IDENTIFICATION DIVISION – Identifies Program Program-ID. <name>. ENVIRONMENT DIVISION – Define computer used, defines files Configuration Section. Source-Computer. T16. Object-Computer. T16. Input-Output Section. File-Control SELECT INFILERead More →

TAL is a high level language that works efficiently with TANDEM NSK hardware to provide OPTIMAL OBJECT PROGRAM performance. Features of TAL: Procedures / Sub procedures / Functions Private data area Recursion Parameters Data types Data sets NonStop process pair programming Pointers Data operations Bit operations Standard functions Compiler Directives Modular Programming Mixed language programming Embedded SQLRead More →

TACL is the standard command interface to the TANDEM nonstop Kernel .In addition of providing the command interface facility; TACL is a high level programming language. TACL consists of commands, built-in-variables and built-in functions. Command is used for interactive work. Built-in functions is used for programmatic work and Built-in variables are used to store environmental information. As a programming language TACL is used to automate system startup and shutdown procedures, run utilities, control subsystem operation, communicates with EMS (event management service). TACL MAIN FEATURES System Access & Information. File Handling. Utility Execution. Built-In Functions. TACL Commands. TACL Variables. Process Execution. TACL MACROS Macro is aRead More →

It is a subsystem which protects databases in online transaction processing (OLTP) environments. The TMF subsystem supports both interactive and programmatic interfaces for commands and event messages. The TMF subsystem manages two major problems: Database consistency. Transaction concurreny. TMFCOM is a command interface and provides interactive commands for all TMF operations. Also allowe you to manage, control and retrieve information about TMF objects such as dump files, and subsystem itslef. TMF concepts: Transactions – A transaction is an explicitly delimited operation or set of related operations that alters the content of a database. The range of transaction is identified within application program by a pairRead More →

Inspect is an interactive symbolic debugger that enables you to isolate program bugs quickly. It is a tool for debugging programs on Tandem Systems like C, C++, SCOBOL, TAL etc. Inspect has three command modes: High-Level Mode – Provides source level access to your program. Low-Level Mode – Provides machine level access. Automatic command mode selection. Note: SCOBOL program can be debugged in high level mode only. Inspect components: The inspect process – Provides the terminal interface to Inspect. The IMON process pair – Monitors the operation of Inspect for an entire system. There is one IMON process pair for each system. The DMON processRead More →

PATHWAY is an application manager. It is a basic environment required to run an application manager. This environment that is made up of the following components: PATHMON: Central controlling process for operations within the pathway or a supervising process that manages all other processes running in a PATHWAY system. PATHCOM: Command Interface to PATHMON process. TCP (Terminal Control Process): Allows requesters to interact with servers. Executes the SCOBOL program in your application and co-ordinate communication between screen programs, I/O devices or processes, Server Processes and PATHMON processes. REQUESTERS: Client, one which sends the request to server for any information. SERVERS: Takes request from Requesters, theseRead More →

It was founded in 1974 and is used where there is need of processing large number of business transactions per second and to record them instantly in a database.These are also known as HP NONSTOP Systems (Including Hardware and Software) are designed to meet all the demanding requirements of online transaction processing (OLTP). These are designed specifically for OLTP. OLTP is the processing of data related to business transaction & activities as they occur. The major feature of OLTP is to keep the database up to date all the times. The unique feature provided by tandem OLTP system is Fault Tolerance, which means to withstandRead More →
