SAS macro variables are stored in memory by default and are deleted when a SAS session ends. In order to use them in a new SAS session, you can save them from the SASHELP.VTABLE view.

The sample code on the Full Code tab illustrates how to save all of the global macro variables created within a SAS session and then recreate them in another SAS session.

Note: The values for SCOPE include AUTOMATIC, GLOBAL, and the name of any macro that contains any local macro variables. Automatic macro variables cannot be restated in subsequent SAS sessions. Local macro variables can be saved, but must be restated inside a macro definition in a subsequent SAS session.

This sample code saves all of the global macro variables from the SASHELP.VMACRO table, and places them into a permanent data set. CALL EXECUTE is used in a subsequent SAS session to restate the macro variables with %GLOBAL and %LET statements.
