I am using a %if statement inside a macro to execute code when &var does NOT match eye or hand. But the code inside the %if is still submitting when it gets to var = eye. How can I write this so that body = &var + 1; does NOT happen when var equals hand or eye?
%macro look (var);
%if &var ne hand or &var ne eye %then %do;
body = &var + 1;

The way you have it currently written with an 'or', any one of the two conditions needs to be true for the statement inside to execute. When you pass in hand, &var ne eye is true, so it executes. When you pass in eye, &var ne hand is true so it executes. What you intend to say is execute code only if both conditions are true - not hand AND not eye.
%if &var ne hand and &var ne eye %then %do;
