Append/Set:
If you want to Add/Append data to Existed/Newly created
Dataset (With same variabls)
EX: you have DATA SETS Like JAN,FEB,MAR........,DEC.
and you want to create data set like "Sales_2010"
you have to use "SET/APPEND" Statements.
MERGE:
If you want add Existed variables to DataSet you have to use
Merge.
EX: If you 2 Dtasets of one person like Personal &
Professional and you want to all details in one dataset
