you can put the estimates in matrices:

local i = 1
foreach var of varlist `outcomes' {
    reg `var' x1 x2...
    mat M`i' = e(b)
    mat E`i' = e(V)
    local i = `i'+1
    }

thanks a lot for the prompt replies. however, i think i didn't explain my
problem accurately.

i'll start from the end result perhaps it makes more sense this way. please
bear with me.
in the end, i would like to have a matrix (to be exported in excel) with
columns:

varname    coeff1    stderr1    coeff2    stderr2....

the variables under varname come from the varlist `outcomes' i described in
the previous email (i.e. local outcomes " an_abbreviated_varlist ").
to obtain the above mentioned matrix, i'm thinking of implementing the
following loop:

foreach var of varlist `outcomes' {
    reg `var' x1 x2...
    now somehow generate a scalar indexed by the position of `var' in
varlist (i.e. scalar1         for first variable, scalar2 for second), equal
to the coefficient of x1
    do the same for the stderror of x1, coeff of x2, and so on
    }

after the loop is done take these scalars and put them into the above
mentioned matrix. the part i don't know how to do is to generate those
scalars


thanks for bearing with me,

Radu Ban
