Hello everyone,
need 1 not works but simple,I want the result as need2, but can't I omiss 'a=1' in need 2?
data have;
a=1;b=2;c=3; output;
a=100;b=20;c=30;output;
a=1;b=20;c=30;output;
run;
data need1;
k=0;
set have;
if a=1 and b=2 then k=1;
else if b=20 then k=2;
run;
data need2;
k=0;
set have;
if a=1 and b=2 then k=1;
else if a=1 and b=20 then k=2;
run;
Thanks
Are you trying to create a counter by a variable?
Your logic is hardcoded, you need to generalize your logic so that it will work in more situations.
if a=1
then do;
if b=2
then k=1;
else if b=20
then k=2;
end;
is equivalent to yor need2 condition.
