data work.expertise;
set work.levels;
if level = . then expertise = 'Unknown';
else if level = 1 then expertise = 'Low';
else if level = 2 or 3 then expertise = 'Medium';
else expertise = 'High';
run;
when i supply level=4 why its taking expertise = "Medium" instead of "High" ?
it gives proper output when i define if condition like " level=2 or level=3 " why so ?
curious to know how sas is processing level=2 or 3 ! Thanks !
3 is always true. It has nothing to do with LEVEL, as if you had coded:
else if (3) or (level=2) then expertise='Medium';
In SAS, 0 and missing values are false, and all other numbers are true.
This syntax would work:
else if level in (2, 3) then expertise='Medium';

SAS is not natural language, it makes fewer assumptions;
else if level = 2 or 3 then expertise = 'Medium';
should be coded as:
else if level = 2 or level = 3 then expertise = 'Medium';
