This works. I wouldn't rule out other solutions.
sysuse auto, clear
tostring rep78, replace
local scatter ""
levels rep78, local(rep78)
foreach r of local rep78 {
local scatter `scatter' (scatter mpg weight if rep78=="`r'",
msize(large))
}
di `"`scatter'"'
Note that once you come out of the loop, your local includes " ", so you
do need
c.d. quotes then. But I don't have a good explanation for why they are
not essential
within the loop. Perhaps the parser can see that the " " are embedded
within the parens.
Not sure.

I am trying to build up a -scatter- command with a -foreach- loop. I
need additional quotes but do not know where to place them. The
problem can be reproduced with the auto data.
. sysuse auto, clear
. tostring rep78, replace
. local scatter ""
. levels rep78, local(rep78)
. foreach r of local rep78 {
local scatter `"`scatter' (scatter mpg weight if rep78=="`r'",
msize(large))"'
}
. di "`scatter'"
(scatter mpg weight if rep78==Unknown function .", msize()
r(133);
As the error message shows, I need additional quotes somewhere. How do
I have to edit the definition of the macro "scatter"? In the end, the
macro should contain the following string, so that I can draw a graph
with the command -graph twoway "`scatter'"-.
(scatter mpg weight if rep78==".", msize(large)) (scatter mpg weight
if rep78=="1", msize(large)) (scatter mpg weight if rep78=="2",
msize(large)) (scatter mpg weight if rep78=="3", msize(large))
(scatter mpg weight if rep78=="4", msize(large)) (scatter mpg weight
if rep78=="5", msize(large))
