CPD generated Clarion code based on the contents of that dictionary and a template called a "model file." Because the model file was a text file, it could be modified (in limited ways) to create custom code. Version 2.0, released in May 1988, was named Clarion Professional Developer (CPD), and included a component named Designer, which incorporated a data dictionary. It cost far less than Professional Developer 1.x. Named Personal Developer, it strictly limited what a user could do, but was adequate for very basic database applications. The dongle was omitted with release 1.1.Īt that time, an even more basic version was sold. This was offset by the ability to create royalty-free applications. Bruce Barrington formed Barrington Systems and released version 1.0.Ĭlarion 1.0 required use of a dongle, at a time when industry sentiment was turning against dongles. Initially it supported databases composed of DAT files which was Clarion’s proprietary ISAM file format. Version 1 produced pseudocode the initial release included a screen designer, an interpreter, an editor, and a debugger. Barrington's goal was to create a language that would be compact and expressive, and would maximize the use of the memory-mapped screen of the IBM PC by creating a screen designer. Clarion was created by Bruce Barrington, one of the founders of healthcare firm "HBO & Company" (later acquired by McKesson Corporation, ) and a small team of developers. The first release of the Clarion language was a DOS product named Clarion 1.0 and was first released in April 1986. Three main Clarion products exist: Professional Edition, Enterprise Edition, and. Many templates have been written by various developers: some are offered as commercial add-ons, and some are free. The templates (from which the code is generated) are provided in source form and developers are free to create their own templates. This mixing of template code and generated code allows the template settings to be updated, and the code regenerated, without loss of the embedded code. This process of embedding code can be done while viewing the surrounding generated code. If the templates are used to generate code, then programmers are able to inject their own code into the generated code to alter, or extend, the functions offered by the template layer. It is possible to create programs fully at the code level ( the so-called 3 Lager), bypassing all code generation facilities. This generation layer is sometimes referred to as 4GL programming. The generator then turns this higher level into code, which in turn is then compiled and linked using a normal compiler and linker. The IDE provides code generation facilities via a system of templates which allow programmers to describe the program from an abstract level higher than code statements. The Clarion development environment ( IDE) runs on the Clarion language. It is compatible with indexed sequential access method ( ISAM), Structured Query Language ( SQL), and ActiveX Data Objects ( ADO) data access methods, reads and writes several flat file desktop database formats including ASCII, comma-separated values ( CSV), DOS (binary), FoxPro, Clipper, dBase, and some relational databases via ODBC, Microsoft SQL Server, Sybase SQL Anywhere, and Oracle Database through the use of accelerated native database drivers, and XML, Clarion can be used to output to HTML, XML, plain text, and Portable Document Format ( PDF), among others.
