DFSMShsm: Update applications that depend on LIST command output
Description
Beginning in z/OS V2R2, the output of the LIST DUMPCLASS command includes a new MINSTACK value, and the position of the existing STACK value in the output has changed. This new and changed output is displayed when OUTDATASET, SYSOUT (the default), or TERMINAL is specified as the destination for the output.
Table 1 provides more details about this migration action. Use this information to plan your changes to the system.
