Dear colleagues I have a data file with several variables each having multiple observations in one record.   The dataline statement has 'car_type'   'car_color'   afterwards three consecutive informations on 'mile'                                   afterwards 'car_dirt' and again three consecutive informations on 'oil'   my strategy was using '@' in order to hold the line and read the multiple observations in do-loops.   The output example shows that only the first variable with multiple observations is read properly.   what am I doing wrong?   all the best Robert   data new; input car $ color $  @; do i = 1 to 3;   input miles @;   output;   end;   input dirty $ @; do j = 1 to 3;    input oil ;    output; end; datalines; VW green   25 35 28 yes 0.25 0.35 0.28 bmw yellow 15 25 18 no  0.15 0.25 0.18 ; run; proc print; run;   OUTPUT               Beob.    car    color    i    miles    dirty    j     oil                      1      VW     green    1      25              .     .                      2      VW     green    2      35              .     .                      3      VW     green    3      28              .     .                      4      VW     green    4      28      yes     1    0.25                      5      VW     green    4      28      yes     2     .   ...
