What does _N_ mean in SAS?

the _N_ value represents the current observation to be output to MyTable. The if condition _N_ = 1 then set SmallTable causes SAS to read a value from SmallTable.

Where in SAS is data step?

The WHERE statement can only be used in DATA steps that use existing SAS data set(s) as input, i.e., a SET, MERGE, or UPDATE statement must exist. If you are using an INPUT statement to read in “raw” files, then you cannot use WHERE. A single WHERE statement can apply to multiple data sets.
