```Thanks again everyone...

Now this may be asking too much, but following the below example of saving the matrix of mean values to variables...does anyone know how to save their corresponding standard errors (SEs) as a matrix and/or variable(s)? Thanks.
[prior example:]
webuse highschool, clear
svyset county [pweight=sampwgt], strata(state) vce(linearized)
svy: mean weight, over(sex)
matrix means =  e(b)
matrix list means
svmat means     // <-- This line creates two new variables

Rebecca,

You can use the -svmat- command to create a variable from a matrix.  From
the examples given previously

webuse highschool, clear
svyset county [pweight=sampwgt], strata(state) vce(linearized)
svy: mean weight, over(sex)
matrix means =  e(b)
matrix list means

svmat means     // <-- This line creates two new variables
