Overview

You can reference macro variables anywhere in your program. Some applications might require placing a macro variable reference adjacent to leading text (text&variable) or trailing text (&variabletext) or referencing adjacent macro variables (&variable&variable) in order to build a new token. When you combine macro variable references and text, it is important to keep in mind how SAS interprets tokens.

Remember that a token ends when the word scanner detects either the beginning of a new token or a blank after a token.

You can place text immediately before a macro variable reference to build a new token. For example, suppose that data sets are stored in a SAS library, using the naming ...
