The following SAS program is submitted:
data WORK.NEW;
do i=1, 2, 3;
Next=cats('March' || i );
infile XYZ
filevar=Next
end=Eof;
do until (Eof);
input Dept $ Sales;
end;
end;
run;
The purpose of the FILEVAR=option on the
INFILE statement is to name the variable
Next, whose value:
A.
points to a new input file.
B.
is output to the SAS data set WORK.NEW.
C.
is an input SAS data set reference.
D.
points to an aggregate storage location. |
