The pstatus command is available only in MP Prism.
Use the pstatus command to display the execution status of the processes in pset set_name or which fit the pset definition set_definition. See the define pset command for a discussion of how to define a pset. If you issue pstatus with no arguments, it displays the execution status of the processes in the current pset. In its output, pstatus aggregates processes that have the same status.
