       1mnice 22m?4mpriorityincr24m?

              Change or return the process priority.  If 4mpriorityincr24m is omit-
              ted, the current priority is returned.  If 4mpriorityincr24m is posi-
              tive,  it is added to the current 4mpriority24m level, up to a system
              defined maximum (normally 1m1922m),

              Negative 4mpriorityincr24m values cumulatively increase the program's
              priority  down  to  a  system  defined  minimum  (normally 1m-1922m);
              increasing priority with negative niceness values will only work
              for the superuser.

              The new priority is returned.

              The 1mnice 22mcommand is not available on 1mWindows22m.
