The following SAS program is submitted:
data test;
set chemists;
jobcode = Chem2
then description = Senior Chemist;
else description = Unknown;
run;
The value for the variable JOBCODE is:
JOBCODE -
-------------
chem2
What is the value of the variable DESCRIPTION?
Given the SAS program, the value for the variable JOBCODE is 'chem2' in lowercase. However, the code checks if jobcode is equal to 'Chem2' with an uppercase 'C'. Since 'chem2' does not match 'Chem2' (because SAS is case-sensitive), the condition fails, and the ELSE part of the statement is executed, assigning the value 'Unknown' to the variable DESCRIPTION.
there is also a missing if statement, here the corrected code: data test; infile datalines; if jobcode = "Chem2" then description = "Senior Chemist"; else description = "Unknown"; input JOBCODE $; datalines; chem2 ;
Unknown is the answer. JOBCODE is chem2 (lowercase). In the IF statement: if jobcode = 'Chem2' then description = 'Senior Chemist';, C is in capital case. Since the condition does not meet, the ELSE statement would be executed.
why are so many code have typos and incorrect syntax. So frustrating and confusing to go through practices this way.
