Return(value) takes only one argument. To return a list,
return(list(x=x,y=y,prob=prob))
I bet the author of help(return) thought that this was implied clearly
enough.
and the warning message in English is not what is quoted here:
f - function() return(x=pi, y=pi)
f()
$x
[1] 3.141593
$y
[1] 3.141593
Warning message:
In return(x = pi, y = pi) : multi-argument returns are deprecated
so they are in fact used. What is puzzling is that anyone is still trying
to use them years after they were deprecated (and as the help page says
they were never documented in S, quite how they ever got into circulation
in R).

Dear Prof. Brian Ripley,
You are absolutely right. The warning message in R for my Chinese Windows
system is Chinese words, so i translate it into english, which maybe not
that exact in the meanings.
Thanks very much.

Re: [R] return(x=x,y=y,prob=prob) hasn't been used in R now?
I don't know what exactly you want the program to do. But if you want to let
the function to return several values in the same time, you have to put them
into a list. E.g. in the following program, the function will return 4
different things, x and y are vectors, prob is a matrix and p is a scalor.
Hope this helps,
Honglian
a-function(x,y)
{
gx-seq(1,x,length.out=y)
gy-gx
prob-matrix(gy,nrow=2)
for (i in 1:y)
{
for (j in 1:y) p-0.1
}
lst-list(x=gx,y=gy,prob=prob, p=p)
return(lst)
}
b=a(10, 20)
