COBOL (/ ˈ k oʊ b ɒ l,-b ɔː l /; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is an imperative, procedural, and, since 2002, object-oriented language.
TELON supported multiple database technologies, including IBM's VSAM, IMS/DB, DB2, plus Cullinet's IDMS. TELON is an application code generator that uses macros to generate COBOL, COBOL/II, or PL/I code that can run natively in the target environment without run-time proprietary code. Developers create screen designs in the TELON Design ...
Records essentially follow the COBOL pattern, consisting of fields of different types: this allows complex internal structure such as repeating items and repeating groups. The most distinctive structuring concept in the Codasyl model is the set. Not to be confused with a mathematical set, a Codasyl set represents a one-to-many relationship ...
Early versions supported IBM's DB2 database, 3270 'block mode' screens and generated COBOL code. In the intervening years the toolset has been expanded to support additional development techniques such as component-based development; creation of client/server and web applications and generation of C, Java and C#. In addition, other platforms ...
For example, Program Control Domain (DFHPC) or Transient Data Domain (DFHTD). The kernel operated as a switcher for inter-domain requests – initially this proved expensive for frequently called domains (such as Trace) but by utilizing PL/AS macros these calls were in-lined without compromising on the separate domain design.
Datacom/DB is a relational database management system [1] for mainframe computers.It was developed in the early 1970s by Computer Information Management Company and was subsequently owned by Insyte, Applied Data Research, Ameritech, and Computer Associates International, Inc. Datacom was acquired by CA Technologies (formerly Computer Associates), which renamed it to CA-Datacom/DB and later to ...
This numbering is generated by Natural during program creation. Line numbers used by the compiler and editors, and can have important logical functions in the programs. Comments can be included in two ways: Full-line comments are identified by a "*" or "**" prefix. Annotated code lines have a "/*" - everything to its right is a comment. Examples:
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 programs using any computer that supports J2SE 1.6.0+ runtime.
