Godwin's law for programmers: "As software development grows longer, the probability of emergence of an improvised in-house scripted language (as bad as Nazis or Hitler) approaches 100%".
The company was founded around 1996. I assume he wrote it because there was no easy way to develop for Win CE back then except for C++/MFC. It did allow the company to hire a lot of cheap developers from well known but not well respected private colleges.
The same code could also be used for the back end supporting services, but he did at least add support for COM interop on the server so we could use any language to actually do the heavy lifting.
They pushed him out around 2011 and I was the only old guy that knew anything about C++/MFC and assembly to maintain it until the company folded.
It was developed around 1996 I think. Replaced with PHP when Yahoo hired Rasmus Lerdorf.
