Imagine we have a binary numeric variable named "employed" that is equal to $2$ if the individual is employed and $1$ if the individual is not employed. We want to create a new variable that is equal to $1$ if employed and $0$ otherwise. What is wrong with this code?

It should be: gen newvar employed $==2$

It should be: gen newvar$==($employed$=2)$

"gen" is not the correct command to construct new variables

It shcyld be: gen newvar$=($employed$=="2")"$
