Subject: st: Dichotomizing a Variable

Suppose I have a variable, abc that consists of: 1 2 3 4 5 5 6 7 8 9. I want
to dichotomize the variable at the median.

generate abcnew = 0
replace abcnew = 1 if abc > 5

What statement do I write that assigns one of the 5s a 0 and the other 5 a 1
in abcnew?

Thanks for the assistance.
