I want to combine datasets 1 (student ID and teacher name) and 2 (type of 
class) to create dataset 3, as shown below.   I don't think it is a simple 
merge.

   Part of the complication may arise from the fact that datasets 1 and 2 have 
different numbers of cases.  I am inclined to suspect I should use "generate" 
in a one-by-one way to insert the data needed from dataset 2, rather than 
merge.

************* 
DATASET 1
Student	          Teacher

Student1	Teacher1	
Student2	 Teacher2	
Student3	Teacher1	
Student4	 Teacher2	
Student5	Teacher1

DATASET 2		
Teacher	       Class Type

Teacher1	a	
Teacher2	b
		
DATASET 3 
Student	        Teacher	        Class Type
Student1	Teacher1	a
Student2	Teacher2	b
Student3	Teacher1	a
Student4	Teacher2	b
Student5	Teacher1	a
