IBM Z Development and Test Environment can be used for education, demonstration, and development and test of applications that include mainframe components. The Z390 and zCOBOL is a portable macro assembler and COBOL compiler, linker, and emulator toolkit providing a way to develop, test, and deploy mainframe compatible assembler and COBOL ...
A mainframe computer, informally called a mainframe or big iron, [1] is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing.
However, many mainframe applications these days have custom web or GUI interfaces. The z/OS operating system has built-in support for TCP/IP. System management, done in the past with a 3270 terminal, is now done through the Hardware Management Console (HMC) and, increasingly, Web interfaces.
Similarly, another popular textbook of the time, Stern and Stern's Structured COBOL Programming, tries to present an implementation-independent explanation of the language, but the appendix giving the full syntax of the language is explicitly for IBM COBOL, with its extensions to the language highlighted.
SPF/PC is an MS-DOS-based text editor and file manager designed to have an interface that was familiar to those using mainframe SPF and ISPF. [1]Later Microsoft Windows-based versions were named SPF/SE and SPF/SE 365. [2]
Document Content Architecture, or DCA for short, is a standard developed by IBM for text documents in the early 1980s. DCA was used on mainframe and IBM i systems and formed the basis of DisplayWrite's file format.
The BSAM application program interface can be compared with the interface offered by open, read, write and close calls (using file handles) in other operating systems such as Unix and Windows. POINT provides an analog of seek or lseek ,and ftell is the equivalent of NOTE .
EntireX is a software product developed and marketed by Software AG. It is primarily an enterprise application integration product, designed to enable application-level integration of Windows clients (desktops, laptops, etc.) with 'legacy systems' (mainframes), packaged systems (such as other Software AG products) and Web services.
