Hello Statalist
I have data on various immunosuppression therapies coded as 1 or 2 or missing(eg given below), where 1=no and 2=yes.

8.	2     1       2       1     2     1 
9.	2     2       2       1     1     1 
10.	2     2       2       1     1     1 
	+---------------------------------------+
I need to summarise this into a variable by patients receiving 1 or 2 or 3 or more type of drugs into a variable. Say all patients in the above example dataset will be receiving 3 drugs, with information on the missing being omitted.  Any pointers or help will be appreciated.
Thanks for your time in advance
