Hi, all.

SAS has a nice way of creating indicator variables from continuous
variables.  Let's say I want an age indicator equal to 1 for respondents
ages 25 to 34 and 0 otherwise. (Missing data are not an issue here.)  In SAS
I would simply type:

age 2534 = (25 le age le 34);

In STATA, however, the only way I know to create the same variable is to use
gen:

gen age2534 = (age>=25 & age < 35)

Question:  Is there a better way to generate indicator variables from
continuous ones?

Thanks,

Deb Garvey
