Thanks Nick. I forgot to mention that I tried with and without spaces,
because the error appears in any case.
. gen rn = rnormal(0,9)
Unknown function rnormal()
r(133);

There is no rule against a variable called -rnormal-, so your reference to -rnormal- followed by a space indicates to Stata that you mean to refer to a variable with that name. You don't have one, so it throws you out in a state of puzzlement with a message that is perfectly reasonable.
