data_null_ is a power of datastep without creating a data set

Answer / akash

The _NULL_ DATA step is a specialized case of the DATA step.
When you use the _NULL_ key word, the DATA statement
processes all statements within the DATA step without data
set
creation1.
Some of the uses of DATA _NULL_ are:

 To create customized reports with and without ODS. The
reports can be routed to the Output window, directly to a
printer, to an external file, or any destination that can be
defined by the FILE and FILENAME statement.

 To create macro variables based on values obtained from
an
input SAS data set or external file.

 To create ASCII data (flat) files for importing into MS
Excel,
MS Access or other programs and databases.

 To execute special functions or call routines available
within
the DATA step, such as CALL EXECUTE
