st: Optimizing recoding procedures

Dear Statalisters,
I am trying to optimize my data recoding procedures (in Stata 11).
With the inlist-function it is possible to reduce the syntax in such a way:
gen x = 1 if z==1
replace x = 0 if x==1 | x==2 | x==3
gen x = 1 if z==1
replace x = 0 if inlist(y, 1, 2, 3)
However, I am looking for functions that allow a reduction in a situation with two variables in the (second) if statement:
gen x = 1 if z==1replace x = 0 if x==1 | x==2 | x==3 | y==1 | y==2 | y==3
and:
geb x = 1 if z==1replace x = 0 if x==1 & x==2 & x==3 & y==1 & y==2 & y==3
Is there a way of doing this via a DIRECT function in the if statement (that is without taking the indirect route via "egen ral" respectively "egen rany")?
Best,
