SAS Macro Facility under Windows

In general, the SAS macro language is portable across operating environments. This section discusses those components of the macro facility that have system dependencies. For more information, see the SAS online Help for the macro facility or SAS Macro Language: Reference and SAS Language Reference: Dictionary.

Note: The words CON, NUL, PRN, COM1 - COM9, and LPT1 - LPT9 are reserved words under Windows. Do not use these reserved words as the name of a macro variable. [cautionend]
