I'm having a clean out and came across some old Clarion programming stuff.  I've got Clarion Professional Developer version 2, Clarion Database Developer version 3 (floppy disks and manuals), Clarion For DOS version 3.1 (floppy disks and manuals).   Also included are a couple of books on Clarion programming, and some Clarion magazines and disks with public domain software.

All of this runs under DOS and is for creating DOS programs.  These may be of use to someone still doing DOS programming.

I really hate to throw away this stuff, it cost me a couple of thousand dollars over the years!  Anyone that can make use of it can collect it from me for free.  Collection from Glenfield on Auckland's North Shore.  PM me here to arrange pickup.

Clarion 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.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. Later on, early releases for Microsoft Windows were historically notable for providing a screen painter and report writer, at a time when most programming languages for MS-Windows required the user to write code to create each screen.Clarion is a data-centric language, meaning that its primary function is the management and manipulation of data. Thus the language has commands that deal directly with the reading and writing of databases. Database Tables are a native data type in the language. Reports, as a mechanism for data output are also a native data type of the language.
