Katy, could you be more specific as to what you have in mind?  Anyway, one 
way might be

gen x = 100 *  dummy_1 + 10 *  dummy_2 +  dummy_3
tostring x, gen(xstring)

I suspect that isn't what you have in mind though, e.g. maybe you want a 
string variable with values like "high" "medium" "low" ?  Perhaps something 
like

. gen y = "high" if dummy_1 == 1
. replace y = "medium" if dummy_2 == 1
. replace y = "low" if dummy_3 == 1
