Given the following raw data records in DATAFILE.TXT:

----|----10---|----20---|----30
Kim,Basketball,Golf,Tennis
Bill,Football
Tracy,Soccer,Track

The following program is submitted:

data WORK.SPORTS_INFO;
length Fname Sport1-Sport3 $ 10;
infile ‘DATAFILE.TXT’ dlm=’,’;
input Fname $ Sport1 $ Sport2 $ Sport3 $;
run;

proc print data=WORK.SPORTS_INFO;
run;

Which output is correct based on the submitted program?

Obs	Fname	Sport1	Sport2	Sport3
1	Kim	Basketball	Golf	Tennis
2	Bill	Football
3	Tracy	Soccer	Track

Obs	Fname	Sport1	Sport2	Sport3
1	Kim	Basketball	Golf	Tennis
2	Bill	Football	Football	Football
3	Tracy	Soccer	Track	Track

Obs	Fname	Sport1	Sport2	Sport3
1	Kim	Basketball	Golf	Tennis
2	Bill	Football	Tracy	Soccer

Obs	Fname	Sport1	Sport2	Sport3
1	Kim	Basketball	Golf	Tennis

Why is the c and not a?

Thanks

The INPUT statement reads line by line. when the first line is finished reading then it goes to second line to look for data untill the INPUT statement finish reading all variable values. If the line has a missng values you have to use MISSOVER in the INFILE.

The belove code gives option A

data WORK.SPORTS_INFO;

length Fname Sport1-Sport3 $ 10;

infile 'datafile.txt' dlm=',' missover;

input Fname $ Sport1 $ Sport2 $ Sport3 $;

run;

proc print data=WORK.SPORTS_INFO;

run;
