If you have mixed types in the cell, that's only possible with a character variable. If your variable is numeric, then UPCASE will definitely not work.</P> Tue, 24 Oct 2017 20:58:37 GMT https://communities.sas.com/t5/SAS-Programming/How-to-change-any-lower-case-in-a-string-to-upper-case/m-p/407076#M99165 Reeza 2017-10-24T20:58:37Z https://communities.sas.com/t5/SAS-Programming/How-to-change-any-lower-case-in-a-string-to-upper-case/m-p/407077#M99166 <P>Thanks - I just preceded that line with newvar = " " and that seemed to work for some reason.</P> Tue, 24 Oct 2017 21:00:07 GMT https://communities.sas.com/t5/SAS-Programming/How-to-change-any-lower-case-in-a-string-to-upper-case/m-p/407077#M99166 Melk 2017-10-24T21:00:07Z
