ReplyDeleteFolks did you realize how the question is asked between 17 and 18.
I think this one asked CHEM3 in capital letter as JOBCODE. Where as in 17 chem3.
If you consider that capital letter has nothing to do then the answer is straight forward C. and my answers sheet says C.
Try this code: the description "Senior Chemist" will only occur with chem3

infile datalines;
input jobcode $;
datalines;

Chem3
CHEM3

data test;
set chemists;
if jobcode = 'chem3'
then description = 'Senior Chemist';
else description = 'Unknown';
run;
Why is D not the answer?
ReplyDeleteAnswer is B. Try this
