The macro facility is a tool for extending and customizing SAS and for reducing the amount of text that you must enter to do common tasks. The macro facility enables you to assign a name to character strings or groups of SAS programming statements. You can work with the names that you created rather than with the text itself.

The SAS macro language is a string-based language. It does not support the use of hexadecimal character constants.
