IPIVOT ;
The IPIVOT statement causes the LP procedure to execute one integer branch-and-bound pivot and pause. If you use the IPIVOT statement while the PROXIMITYPAUSE= option is in effect, pause interferences may occur. To avoid such interferences, you must either reset the PROXIMITYPAUSE value or submit IPIVOT; RUN; instead of IPIVOT;.
