Transposing Datasets
SAS datasets are organized into variables (columns) and observations (rows). Sometimes we need to change the organization of our data. Transposing a dataset means to change observations in a row into observations in a column, or to convert variables into observation and observations into variables.

The Transpose Procedure
The Transpose Procedure transforms an input dataset.
In the BY statement, list any grouping variables that should remain variables in the transposed dataset. The dataset must be sorted according to the variables listed.
In the ID statement, list a variable whose observations will become the new variable names in the transposed dataset.
In the VAR statement, list the variables whose observations will be transposed. Note: unless listed in the VAR statement, character data types are not transposed.
