Katja --

This will work in Stata8 if you put a $ before S_4

     . bs "inequal7 i11101" $S_4, reps(10)


The problem with

     . bs "inequal7 i11101" r(gini), reps(10)

is that the author of -inequal7- returned the values as locals, rather than
scalars, and they appear as string values rather than numeric values when
evaluated via -r()-, thus the type mismatch.
