And then there's pdksh - think of it as a broken implimentation of ksh...
pdksh sets the variable $KSH_VERSION...
If you're on a "free" system (Linux, possibly BSD as well), you will have this instead of the real ksh, due to the license.

I always install the real ksh though, since it works better.
