Dear

I am trying to find a function that i can be used in the second 'if' statement. Please suggest.Thank you

in the second if statement, i am trying to find if all three variables missing or all three variables ='UNKNOWN' then set the 'd' variable missing.

my code;

data two;

set one;

if a="NEGATIVE" and b="NEGATIVE" and c="NEGATIVE" then=d='yes';

if cmiss(a,b,c) =3 or (a='UNKNOWN' and b='UNKNOWN' and c='UNKNOWN' ) then d='missing';

else d='no';

It's not clear to me what the question is. You haven't actually asked a question.

I suspect that what you mean to do is :

data two;
set one;
if a="NEGATIVE" and b="NEGATIVE" and c="NEGATIVE" then d='yes';
else if cmiss(a,b,c) =3 or (a='UNKNOWN'  and b='UNKNOWN'  and c='UNKNOWN' ) then d='missing';
else d='no';
run;

I'm not sure you meant to re-use the variable name D all the time. But here is an approach you can use.

if a=b=c then do;

if a in (' ', 'NEGATIVE') then d='yes';

else d='no';

end;
