Yes, IIRC, Clipper 5's big marketing point was `aeval`! (short for array eval, array.map in modern langs).

Clipper also had a huge array of third party libraries, I fondly remember Nanfor, Grumpfish, and SuperLib.

If you want to see some code, here's a repo of one of my Clipper projects: https://github.com/jasim/EasyAccounts

There is also The Oasis mirrors which have a large cache of Clipper code: https://harbour.github.io/the-oasis/docs/
