Answer / Meetha Lal Meena

In SAS, both the SET and DATA statements are used to read data. However, they handle the 'drop' option differently:
1. SET Statement: The DROP=data-set option removes variables from the current SAS data set, but not from the original data set being read.
2. DATA Statement: The DROP statement removes variables from the newly created SAS data set. It does not affect the original data being read.
