The Stock and Debtors Database Schema below contains a hyperlink to a full development package of Wordtech's multi-user Quicksilver compiler (v1.3b) and dBXL (v1.3) a command-line dBASE III PLUS interpreter.
With the dissolution of Wordtech Systems Inc management team by Borland many years ago, these programs have been listed for some time as "abandonware" and are accordingly made available here to be freely copied.
Click here for some notes on dBXL's handling of numeric fields (i.e. double precision).
Click here for further understanding of what a compiler of dBASE will do. When the writer of the article talks about Clipper and Harbour which generates C source code, the statements apply equally well to Quicksilver (with its "d-Code" source), and when Quicksilver is combined with the dBXL database platform for development, maintenance and upgrade purposes, it provides a powerful package.
The applications listed below are multi-user business management applications that ran on 16-bit DOS, and since 1995 have run on all versions of 32-bit Windows (including Windows 10) inside a well-behaved VDM window, without users needing to be online to the Internet.
In 64-bit Windows 10 (also 7 8 and 11) the applications run inside DOSBox and vDos, using a text to PDF conversion utility to vary the font size for Printouts and Reports.
Other applications are available. View the "About us" link above for further background.
