st: collapsing in a way to display the different values for a variable in a row

Dear statalist users I am dealing with this problem:
I have a huge dataset where one of the variables lists different kind of medication ("treatment", string variable). Each person can take different medication so for every value of the variable "idperson" I have several records, each with a different value of the variable "treatment". Just to give you an idea this is how the dataset looks alike:
idperson date treatment
1 01February2000 a
1 15March2001 b
1 c
2 b
2 c
2 e
2 d
3 a
Is there a way, maybe using collapse to have for each id person as much date and treatment variable as the real records for each idperson are?
something like:
idperson date1 treatment1 date2 treatment2 and so on...
thank you in advance!
