data test;
a1= "aa";
a2= "bb";
a3= "cc";
b1= "bb";
b2= "bb";
b3= "cc";
/*After comparison*/
comp1= "No";
comp2= "Yes";
comp3= "Yes";
run;
What I am looking for -
if a1 in (b1,b2,b3) the comp1 = 'Yes';
else comp1 = 'No';
as we don't find the match for a1 in any of (b1,b2,b3) then comp1= "No" and our next scenario will be
if a2 in (b1,b2,b3) the comp1 = 'Yes';
else comp2 = 'No';
now we found a match for a2 in b1 then comp2= "Yes" and will not include that column where we found the matching value in next scenario and our next scenario will be
if a3 in (b2,b3) then comp3 = 'Yes';
else comp3 = 'No';
now we found a match for a3 in b2 then comp3= "Yes" and our next scenerio will be if there are anything else
if a4 in (b3) then comp3 = 'Yes';
else comp3 = 'No';
Thanks!
If the values of the a-variables are that simple, this should work:
data want;
set test;
length compare1-compare3 $ 3;
array a_vars[3] a1-a3;
array cmp[3] compare1-compare3;
cmp_string = catx('|', of b1-b3);
do i = 1 to dim(a_vars);
if findw(cmp_string, a_vars[i], '|', 't') > 0 then do;
cmp_string = tranwrd(cmp_string, a_vars[i], ' ');
cmp[i] = 'yes';
end;
else do;
cmp[i] = 'no';
end;
end;
drop cmp_string i;
run;
