The following SAS program is submitted:

Which one of the following is the value of the EVENT variable?
A. 01012000
B. January 1st
C. . (missing numeric value)
D. The value can not be determined as the program fails to execute due to errors.

Answer D

The if date = '01012000'd then event = 'January 1st'; has a syntax error.
The date constant '01012000'd should be ‘01Jan2000’d.

data work.TEST;
infile cards;
input @1 date mmddyy10.;
if date = '01jan2000'd then event = 'January 1st';

Any more on this one Sasguru? Why do you have to use '01Jan2000'd for the date constant?

Geoff said...

That's just the way it was programmed. The date constant can only recognize and convert date values given in the format 'ddmmmyyyy'd . It doesn't recognize the given series of numbers as a date.

My answer is D:
Here there is a syntax error.
The date constant displayed as '01012000'd should be ‘01Jan2000’d.
