SAS proc report ensure that sections do not split between pages

Question

I'm creating rtf report and group data by Var that is not into final report. I also added the split line between groups

 column var stat group1 group2 group3;
  define var/'' group noprint;
  define stat/display "Statistic" ;
  define group1/display "Group 1" ;
  define group2/display "Group 2" ;
  define group3/display "Group 3" ;
  
   compute after var;
    line '';
   endcomp;

How to ensure that a Var group does not break between pages?

If there is no room for whole group, the whole group should be moved to the next page
