IF can only be used in a DATA step
Many IF statements can be used in one DATA step
Must read the record into the program data vector to perform selection with IF
WHERE can be used in a DATA step as well as a PROC.
A second WHERE will replace the first unless the option ALSO is used
Data subset prior to reading record into PDV with WHERE
