I already told you! I said "you could combine -functions- and -twoway function-".
That means: go -help functions- and then look at -density functions- (which in this case includes distribution and quantile functions).

Nick,
Thanks,
> . twoway function normden(x,1,1), ra(-5 5) || function normden(x), ra(-5 5)
is exactly what i was looking for.
One more question, what do i have to type instead of "normden" to receive the cdf?
Or where can i find all these "abbreviations"?
