Adding Variables to data set

[cpmcn19]

Attempting to create new variable top breed based on dog data set. Trying to set top breed to 1 if the breed contains the words in the if statement , and 0 if not. Currently code is: 

data_aac_new_variable;

set = dog_data;

if breed = "Bulldog", "Lab", "Terrier", "Shepherd", "Beagle" then Topbreed = 1;

else = 0;

run;

if breed in ("Bulldog", "Lab", "Terrier", "Shepherd", "Beagle") then

use the IN operator

data _aac_new_variable; 

set dog_data;

if breed in ( "Bulldog", "Lab", "Terrier", "Shepherd", "Beagle") then Topbreed = 1;

else = 0;

run;

Few Issues With the code corrected:

data_aac_new_variable;

set  dog_data;

if breed  in ("Bulldog", "Lab", "Terrier", "Shepherd", "Beagle" ) then Topbreed = 1;

else Topbreed = 0;

run;

data_aac_new_variable;

set = dog_data;
if breed = "Bulldog", "Lab", "Terrier", "Shepherd", "Beagle" then Topbreed = 1;
else = 0;

run;

Thanks for the reply. Is there anyway to add a contains to the if breed in statement? Some data says Lab whereas other data says Labrador

Try :

data _aac_new_variable;

set  dog_data;

if breed  in ("Bulldog",  "Terrier", "Shepherd", "Beagle" ) or breed =:'Lab' then Topbreed = 1;

else Topbreed = 0;

run;

You can reduce this to one statement if you use a Boolean expression:

Topbreed = (if breed in ("Bulldog", "Terrier", "Shepherd", "Beagle" ) or breed =:'Lab');
