29. The following SAS program is submitted;
data work.info;
infile 'datafile.txt';
input @1 company $20. @25 state $2. @;
if stat='' then input @30 year;
else input @30 city year;
input numemployees;
run;
how many raw data records are read during each iteration of the data step?
the answer is 1 but i think it's 2 since there's no @ at the if-then cycle.
