The ARM log is an external
output file that contains the logged ARM transaction records. The
ARM log gathers transaction information for the internal SAS processing
transactions (depending on the value of the ARMSUBSYS= system option)
and for user-defined transactions (using ARM macros).
You can change the location
of the ARM log after initializing an ARM subsystem. Any records that
were written to the ARM log in the old location are not copied to
the ARM log in the new location. Therefore, you should issue ARMLOC=
before initializing the first ARMSUBSYS= so that all records are written
to the same ARM log.
