The SAS book I am using appears to only instruct on how to create variables using mathematical functions. Can I create a variable using an if-then statement? How would I code that input?</P> Tue, 16 Jan 2018 18:17:38 GMT https://communities.sas.com/t5/SAS-Programming/Adding-Variables/m-p/428117#M105661 andrewfau 2018-01-16T18:17:38Z https://communities.sas.com/t5/SAS-Programming/Adding-Variables/m-p/428119#M105662 <PRE><CODE class=" language-sas">if variable1=variable2 then newvariable=1; else newvariable=0;</CODE></PRE> Tue, 16 Jan 2018 18:23:23 GMT https://communities.sas.com/t5/SAS-Programming/Adding-Variables/m-p/428119#M105662 PaigeMiller 2018-01-16T18:23:23Z https://communities.sas.com/t5/SAS-Programming/Adding-Variables/m-p/428120#M105663 <P>Thanks!
