You don't need to fire up -ds- beforehand. This can thus be reduced to
local i = 1
foreach var of var * {
ren `var' var`i'
local ++i
}
In fact you don't need a loop. With -renvars- from the Stata Journal
(-search renvars- for location) you can go
renvars \ var1-var`c(k)'
c(k) is held by Stata as the number of variables -- see results of
-creturn li- and it has a local macro persona `c(k)'.
Naturally -renvars- is doing the loop on your behalf. It also checks for
name problems.
If Mai does not want all variables renamed, then the advice is modified
accordingly.

local i = 1
