We have tons of shareware utility program and samples written in language and / or for Clipper language.
And tons of them was compiled and published in the legendary internet site by sainted legendary community guru Phil Barnet (RIP). After Phil, this site cloned by Harbour gurus, many thanks to them.
Of course most of that materials are obsolete. But some of them are ageless.
As an example: Click! is a Clipper language source code reformatter. This is much more than a simple reindenter, but actually reestablishes spacing between elements in the lines of code and creates function cross reference charts. Fully documented and configurable.
Viva Clipper 😀
