Hi, i need to count the number of observation that meets 2 conditions: i need to count the observations if column a is valued x and column b is valued y. Can you help?
That is the number in the last observation.
Or you can use PROC FREQ.

if a='x' and b='y' then count+1;
Is that what you want?
by using proc freq statement , you count the no of observation
