I have several records per id: At subsequent times my patient
have received the medication amed or bmed
In the last record within id I woul'd like to generate
a variable abmed wich will be 1 (or some value x) only if the  patient
has in the prior records experinced the use of both amed and bmed or will
be 0 otherwise. 

id time amed bmed abmed
