When you use ARM macros, you must define user metrics
and correlators. You can use your existing programs that contain ARM
macros and continue to get similar results written to the ARM log
or written to the SAS logging facility. However, changing the ARM
macros to performance macros is recommended when using the SAS logging
facility. To compare the features of ARM macros and performance macros,
