The contents of the raw data file size are listed below？
72 95
the following program is submitted:
data test;
infile 'size';
input @1 height 2. @4 weight 2;
Which one of the following is the value of the variable weight in the output
data set?
A 2
B 72
C 95
D .(missing numeric value)
the answer is A. I have tried this program, the result was 2.
Then I changed 2 after weight to 1, the result is 7.
Weight should read valve @4, right?
Thanks a lot. | g*******y

"weight 2" is column input not formatted input. | j******1
