Clarion CPD 2.1Версия реализации Clarion CPD языка программирования Clarion
CPD 2.x was a database solution with everything required for screens, reports, databases and help files. A version of Clarion 2.x for end-users, Clarion Personal Developer, was also released just for the business user creating his own personal applications. Around the same time period, Clarion released Clarion Report Writer. This was created as both a stand-alone product for end-users of Clarion Personal Developer and users of programs written by developers with CPD, and as a built-in program bundled with Clarion Professional Developer version 2.1 released in 1989.
