Hi There, Just having a problem with SAS not recognising one of my variables whilst I am trying to encode a new variable. Basically the code looks like: if CTA_LAD=1 OR CTA_CX or CTA_RCA=1 then CTAPP=1; else CTAPP=0; However, SAS seems to be creating a new variable for CTA_CX filled with missing values. As far as I can see I am typing the exact variable name as it appears in my original datasheets and the SAS output. It is not doing this for any of my other recoding steps. Thanks in advance for your support!
