Hi All,

I seem to have a problem with the command fndmtch2.
My data is a huge sample of companies. They have the form of:

Firms	Inter	Owner	match
c	r	g	0
c	r	t	1
b	t	r	1

I want find whether companies that are "Owners" are included in the category 
of "Inter" also. I run the command fndmtch2 which gives me the variable "match"
The command I run is:
fndmtch2  Owner Inter, generate(match3) count miss

What I do not understand is why isn't match=2 for the case of the 3rd observation since the element of "r" can be met twice (1st and 2nd observation) in the "Inter" variable. Thank you very much!

Regards,
Socrates
