The variables in the BY and COPY statements are not transposed. TOTSPLIT
contains the variables Program, Subject, Time, and Strength with the same
values that are in SPLIT. The BY statement creates the first observation in
each BY group, which contains the transposed values of Strength. The COPY
statement creates the other observations in each BY group by copying the values
of Time and Strength without transposing them.
