Answer Posted / chandrakanth
_null_ will act like any other data step but it would not create any data set.
_all_ will select all the variables in a particular data set.
_n_ is the automatic variable generated by SAS which counts the number of loops SAS moved to the top of data set
(but some people say it is total number of observations which is not always true)
