 | | In fact, SAS is not really a single program, but rather a system that allows you to take data in any form and access, manage, analyze, and present it according to your needs and level of expertise. |
 | | SAS can read your data no matter how it looks in the file, but in the simplest case, data is either aligned in columns ("column" format) or separated by spaces ("list" format), as explained here. |
 | | SAS stores permanent data sets in operating system files, but rather than storing data sets in a plain-text form, SAS stores data sets in a highly efficient special format (known as data set format) that varies depending on the type of workstation you are using. |
