Gag, you call either what Bruce or I sent elegant???

A slightly obscure, but so $%^ng cool it is truly evil and probably
even diabolical approach!
Drum Roll.......;-)

COMPUTE # = # + ANY(1, drug1<>lag(drug1) ,  drug2<>lag(drug2)  ,
drug3<>lag(drug3)  ,drug4<>lag(drug4)  ).
compute combo=#.

Now that's elegant and simple....
