Dear Statalisters,

I am wondering whether it is possible to reference the individual
elements of a (local) macro by a number. For example, if I have the
local macro x "var1 var2 var3". How would something like reg y `x'[3]
work.

Long explanation:

I would like to estimate a number of models with different dependent
and independent variables. The control variable varies with the
dependent variable. I would like to use some kind of loop structure
(since I want to do a lot of estimations). so, I have defined two
macros. Lets say that they each have three elements.

local depvars " depvar1 depvar2 depvar3"
local controlvars " controlvar1 controlvar2 controlvar3"

I would like to do something like that

i=1
foreach c of local depvar{
reg `c' `controlvars'[i]
i++
}

Thanks for your help!


R.
