That's why I said "better for a short list". Typing -inlist()- itself has an overhead.

Won`t the typing of the pipe | symbol _and_ the variable name for each
comparison get tedious for more than three arguments? -inlist()- requires
only an additional comma...
Nick Cox
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.
