When a program is finished referencing the array in the way you specified on CSRIRP, use CSRRRP to remove the definition. The following example tells the system that the program in Defining the range of the area has stopped referencing the array. low_address and size have the same values you coded on the CSRIRP service that defined the reference pattern for that area.

CSRRRP  with low_address of ARRAY1(1,1)
             size of 1024*1024*8 bytes
