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.
IBM Db2 Community Edition is a free-to-download, free-to-use edition of the IBM Db2 database, which has both XML database and relational database management system features. Version 11.5 provides all core capabilities of Db2 but is limited to 4 virtual processor cores, 16 GB of instance memory, has no enterprise-level support, and no fix packs ...
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 ...
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 ...
It is implemented from many languages by making calls to a software stub, DFSLI000. This stub has entry points to handle a variety of programming languages, e.g., calling CBLTDLI from a COBOL program. This stub is linked to the calling program, passes on the request to the IMS system, and returns the results and a status code.
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 ...
GnuCOBOL translates a COBOL program (source code) into a C program. The C program can then be compiled into the actual code used by the computer (object code) or into a library where other programs can call (link to) it. On UNIX and similar operating systems (such as Linux), the GNU C compiler is used for this process.
The Data Base Task Group (DBTG) was a working group founded in 1965 by the Cobol Committee, formerly Programming Language Committee, of the Conference on Data Systems Language . It was initially named the List Processing Task Force and later renamed to DBTG in 1967. The DBTG was chaired by William Olle of RCA. [1]
