data work.staff;
JobCategory = ‘FA’;
JobLevel = ‘1’;
Jobcategory = Jobcategory || JobLevel; run;
Which one of the following is the value of the variable JOBCATEGORY in the output data set?
Answer: A
how is it option A?

data work.staff; JobCategory = 'FA'; JobLevel = '1'; Jobcategory2 = Jobcategory || JobLevel; Jobcategory = Jobcategory || JobLevel; output; JobCategory = 'FAA'; JobLevel = '2'; Jobcategory2 = Jobcategory || JobLevel; Jobcategory = Jobcategory || JobLevel; output; run;
