The utility must be run on a supported release of z/OS®, and have High Level Assembler (HLASM) 1.3.0 or later, and a supported release of SMP/E. If your system does not have the required level of HLASM or SMP/E, you can use STEPLIB DD statements to access HLASM in the target system's SASMMOD1 data set, and SMP/E in the target system's SYS1.MIGLIB data set.
