WHERE vs IF

The WHERE statement works before observation are brought into the data step(that is the PROGRAM DATA VECTOR) .

The IF statement works on observation that are already in the data step.

The WHERE statement is not executable, but the IF statement is

The WHERE statement operates only on observations in SAS data sets, whereas the IF statement can operate either on observations from existing SAS data sets or on observations created with an input statement.

If a BY statement does not accompany a SET or MERGE statement, the WHERE and IF statements usually produce the same result

In almost all cases a WHERE statement is more efficient than an IF statement(observations do not have to be moved into the PDV)

The WHERE statement, but not the IF statement can be used in SAS PROCS .
