I hadn't seen the combination of the ## notation with the parenthesis like Kit used here.

Safe to assume that creates all possible 2-way interactions of G2 with each var inside the parentheses... but not the fully factorialized model?

In my last posting I suggested

regress y i.G2##(ov edu wealth ovxedu ovxwealth)  

This should have been written

regress y i.G2##c.(ov edu wealth ovxedu ovxwealth)  

to make clear that all of the variables listed are continuous.
