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 receive 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, see
Comparing the SAS 9.1 ARM Interface with the SAS 9.4 ARM Interface.
