Both Michael Blasnik and Ben Jann suggested
forval i = 1/20 {
local mac`n' = x[`n']
}
In some circumstances that could bite. Evaluating
rather than copying could lose parts of long
strings and/or leading blanks. A more general
solution is
forval i = 1/20 {
local mac`n' `"`=x[`n']'"'
}
Note that
gen obs=_n
forv n=1/20 {
qui su x if obs==`n', meanonly
local mac`n' = r(mean)
}
can be replaced by almost the same
solution, thus avoiding the triple inefficiency
of an extra variable, a repeated -summarize-,
and a -summarize if- to boot:
forv n=1/20 {
local mac`n' = x[`n']
}
