If you know Clipper/XBase++, please write code for some of the tasks not implemented in Clipper/XBase++.
The Clipper Language was written originally to create executable .EXE files out of the code written for dBase III from Ashton-Tate, which was an interpretative language.

The original writers of Clipper were Ashton-Tate employees that formed a company named Nantucket. The story goes, while sitting in a bar on the island of Nantucket, in MA, and looking at a painting of a Clipper Ship.

Later on, Nantucket was bought by Computer Associates who discontinued maintaining Clipper (last version was 5.3) in 1997.

I believe it was the most powerful relational database language of it's time and it is still in use by some large corporations because of it's simplicity and reliability. When the Windows world came into the scenery, several companies wrote languages that are near 100% compatible with Clipper. Two very well use are XBase++ and xHarbour.

Before dBase came about, to find a record in a table you had to do a binary sort. One of the big features, among others, of dBase was that it could find one record out of a billion by doing only 3 comparisons (on a 4.7 MHz computer) that took less than one second using index files as reference. They also invented the DBF file structure which carries the structure of the table internally in record # 0, also known as the phantom or ghost record.
