This example shows data step and macro examples of the loop exit verbs:
- continue: skip to 'end;' statement, where iteration happens
- leave: exit loop
DATA _Null_;
do I = 1 to 3;
put I= 'pre-test';
if I le 2 then continue;
put I= 'post test';
end;
put 'done continue: ' I= ;
do J = 1 to 3;
put J= 'pre-test';
if J gt 2 then leave;
put J= 'post test';
end;
put 'done leave: ' J= ;
stop; run;
%Macro Do_Tests(i=,j=);
