I agree with Martin Weiss. 

-inlist()- in Stata appears to be the equivalent of IN in SAS. 

I also agree with Anisa Shyti, correcting a typo: 

cond(x == 3 | x == 4 | x == 5, 1, 0) 

is another way to solve the problem, but better for a short list. Indeed 

x == 3 | x == 4 | x == 5 

is yet another way to do it, as the expression just above evaluates to 1 or 0 any way.

let me be more precise: in the condition should be cond(x=3 |
x=4 | x=5, 1, 0)  - it depend on the condition one needs to set - I
was giving a handy example. The cond(.) is pretty flexible.
