  2. Specify column locations for each variable as needed by the software you are using.
Note: SAS and SPSS programs need to be used to convert ASCII into SAS and SPSS datasets. How to use the ASCII data varies from one software package to another. Column positions for each variable usually have to be specified. Column positions for each variable can be found in the documentation for each year’s data.
