Easiest way of deleting line based on row number

[jackice]

Hi, Im using SAS University Studio 3.4, after 10 years of not using it. 

The snippets Filter doesnt allow to delete or filter out data line base on the sas created obs#  

I wish to use a simple data net set old if then delete statement but using the OBS# as the criteria 

Can somoene pls give me the code I need for that? 

THANKS!

I believe you could do something like this to delete observation #1. _n_ is an automatically generated variable in data steps that's dropped from the output.

data newtable;

  set oldtable;

  if _n_ ne 1;

run;

ill try that thanks - what “ne” stands for exactly pls?

Its a comparison operator - NE - Not Equal

They're documented here:

"Not equal to", scroll to comparison operators
