Viewing the Values of All Current Macro Variables

When developing or debugging a SAS application, it is often useful to check the values that have been assigned to Macro variables.

The easiest way to do this is to simply use the following command:

%put _ALL_;

This will list the current value of every macro variable within the SAS log.

In addition to _ALL_ you could use any of the following:

• _USER_ to list only user defined macro variables;
• _AUTOMATIC_ to list those defined by the SAS system;
• _GLOBAL_ to list all session wide macro variables (global symbol table);
• _LOCAL_ to list those macro variables local to the executing macro.
