What type of variables are designated as Display variables?

Display variables in SAS refer specifically to character variables. These variables are typically used to store textual data that needs to be presented in a readable format. When generating reports or output, display variables serve the purpose of conveying information in a way that is easily understood by the end-user.

Character variables allow for the inclusion of letters, symbols, and any alphanumeric data, making them ideal for descriptive labels, names, or categories that require more than just numbers. Numeric variables, on the other hand, are primarily used for mathematical calculations and are less suited for display purposes where textual clarity is essential.

In SAS programming and reporting, the emphasis on character variables as display variables ensures the output is user-friendly and aesthetically pleasing, aligning with the requirements of effective data presentation.
