st: single elements of varlist

["a.carrozzone@libero.it" <a.carrozzone@libero.it>]

Dear Statalist,

I am new to programming and I have a basic problem. I need to refer to the 
single variables in "varlist" and I am not sure how. For example, I might to 
get the sum of: the mean of the first variable, the median of the second 
variable and the standard deviation of the third variable.

Thanks a lot for any feedback,

Andrea



program define myprog, rclass
syntax varlist
get the mean of variable 1
get the median of variable 2
get the standard deviation of variable 3
return scalar results=(sum of the previous three values)
