Clarion definition generator#

It is notable as being an early (although primitive) Computer-aided software engineering tool for MS-DOS with support for defining relationships between data and automatically generating application code. Advanced Clarion programmers can create their own templates, or edit the existing ones.Ĭlarion is historically notable as being one of the first computer languages for MS-DOS that provided a 4GL screen painter, report writer and native database access.

An 'embeditor' shows the developer the code that will be generated and embed points where the developer can enter their own hand-code in the context of the template generated code.

Clarion definition generator#

One of the Clarion Development Environment's primary features is its use of 'templates' which are used in conjunction with a code generator (named AppGen) to produce much of the repetitive, time consuming code that is typically required when producing an application. It is compatible with ISAM, SQL and ADO data access methods, reads and writes several flat file desktop database formats including ASCII, CSV, DOS (Binary), FoxPro, Clipper, dBase, or all SQL RDBMS databases via ODBC, MS SQL Server, Sybase SQL Anywhere and Oracle through the use of accelerated native database drivers, and XML, Clarion can be used to output to HTML, XML, plaintext, and PDF, among others. Clarion Developer(s)Ĭlarion is a commercial, 4GL, multi-paradigm, programming language and Integrated Development Environment from SoftVelocity used to program database applications.
