using STATA 10

included an interaction of var1 (coded as 1,2,3) & var2 (coded as
1,2,3)  in my model

xi: regress i.var1*i.var2

the two variable have more then one level so the lowest level of var1
& var2 will be omitted so the question is

i want to include level 1  of var1 with different levels of var2 (2 & 3)

hope my question is clear!
