This is not a matter covered by an FAQ because it's just a matter of standard syntax as explained in the help and the manuals. 

Think about it from Stata's point of view. Only if you write -rnormal()- with no space -- and arguments supplied within () -- does it know that you want a function with that name. 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. 

set obs 100  
gen rn = rnormal(0,9)

I would like to know if there is a function similar to this that I
found in R: norm <- rnorm(100, 2, 5)
The trick is to generate a variable that contains 100 values with are
normal distributed with mean 2 and stdev 5.

I found that rnormal is a function in Stata, but I am not sure about
the way to write the sintax to produce that outcome. I tried with:
generate rn=rnormal (0,9) but a message telling me rnormal is not
found appeared.

I looked into FAQ but there are no related issues...
