Answer Posted / latha sunkara
When you use the POINT= option, you must include a STOP
statement to stop DATA step processing, programming logic
that checks for an invalid value of the POINT= variable, or
both. Because POINT= reads only those observations that are
specified in the DO statement, SAS cannot read an end-of-
file indicator as it would if the file were being read
sequentially. Because reading an end-of-file indicator ends
a DATA step automatically, failure to substitute another
means of ending the DATA step when you use POINT= can cause
the DATA step to go into a continuous loop.
