There are at least two ways to read data into SAS when there are multiple
lines of data per subject in the raw data file. In the first example
below, a / is used between the variables for each line. This is handy when
there are only a few lines of data per subject. The second example shows
the use of the # symbol to denote the lines on which the variables following it
can be found. This method is more useful when there are many lines of data
per subject.
* 2 lines of data per subject; data temp; input a b c / d e f; cards; 1 2 3 4 5 6 1 3 5 2 4 6 ; run; proc print data = temp; run;
Obs a b c d e f 1 1 2 3 4 5 6 2 1 3 5 2 4 6
* three lines of data per subject; data temp2; input #1 a b #2 c d #3 e f; cards; 1 2 3 4 5 6 1 3 5 2 4 6 9 8 7 6 5 4 ; run; proc print data = temp2; run;
Obs a b c d e f 1 1 2 3 4 5 6 2 1 3 5 2 4 6 3 9 8 7 6 5 4
