<humor> Why not? If Microsoft can call Windows versions before Win 95 an operating system, I think this qualifies. ;-) </humor>

In all seriousness, if there's no task scheduler or multitasking capabilities in this software (and I must admit I haven't poked at it enough to determine whether there is or not), it's not much of an operating system. It kind of reminds me of when I was 12 and thought I'd make an "operating system" using QBasic. (What I ended up with was little more than a glorified text-based, menu-driven program launcher. But, hey, I was 12.)

You'd be surprised what people will build with a host environment-bound language and then call an operating system. Brings back memories of VB6 on PlanetSourceCode.

Nifty, unix-like command-line interface in Javascript.
