You are retaining the wrong variables. You used

retain Name Subject Marks;

Try 

retain maths1 english1;

You may also want:  KEEP name maths1 english1; so those are the only values kept in the output data set.

If you Retain a variable that is in the data set used on a SET statement the value in the data set is reset for each record read.
