I had the same 'unknown function' issue when attempting to run

egen newvar = cond()

However, I had no issues once I used gen instead of egen. See if gen works for you too.

gen newvar = cond()

Late to this party, but #17 is a different and soluble problem from most in this thread. cond() is a general Stata function, not an egen function, and using generate not egen is indeed the way to go.
