How to add a new column to existing dataset

[Cruise]

Hi, I'd like to add new variable to the existing dataset. Below attempt didn't work. I'll appreciate your help. Thanks in advance.

data data;
input county code;
datalines;
1	83	
1	83	
1	83	
1	83	
1	83	
1	83	
1	83	
1	83	
1	83	
;

data data1; 
input risk;
datalines;
0 0.0025 0.005 0.025 0.05 0.1 0.25 0.5 0.75
set data; 
run;

Here's a modified version of your code that should work as you intended:

data data1;
	set data; 
	input risk;
datalines;
0
0.0025
0.005
0.025
0.05
0.1
0.25
0.5
0.75
;

Two of the primary problems with your code were the orientation of the datalines data (if you want each value to be attached to a different observation, it needs to go on a new line) and the missing semi-colon after the datalines data was complete. The DATALINES statement is also intended to be used as the very last part of a data step.
