I think you're right in finding the help 
unclear. I suggest a wording more like 

string(n,"%fmt") converts n into a string using 
%fmt numeric display format. 

What was found with an early version of -tostring- 
was that users missed precisely this point, 
so a trap was put in to catch the error. Any 
string format is just bounced back at the user. 

-tostring- is pertinent, because it's another way 
to do it:

. tostring a1, gen(y) format(%16.0f) 

There's no gain in terms of what you type, but 
there are some advantages, like that mentioned, 
and some other safeguards. 

-tostring- was added to official Stata on 13 August.
