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")?
