I am not aware that you can do this K-S in Stata. 

With this concern in mind, other numerical 
and graphical alternatives are 

some variant on Wilcoxon-Mann-Whitney
(e.g. -ranksum-, esp. the -porder- option)

-qqplot- 

-somersd- 

-qplot- 

-distplot- 

For the last three, use -search- to identify 
locations.
