I have patient encounter file with more than 13000 records. File structure is like this.   No  Problemtype1     problemtype1b    problemtype1c  ...  problemtype49   prblemtype49c   outcome1   outcome1b ...  outcome49c --------------------------------------------------------------------------------------------------------------------------------------------------------------    1          aa                            bb                         cc                       aa                 bb                   solved          rejected           denied  2 ... 13000     I need to count respective outcomes if problemtype is 'aa'.  I am using following sample code.       data test2; set testdata;         array problemType [4,3] ProblemType1 - ProblemType8 ProblemType1b1-ProblemType1b4;         array final_outcome {4,3} final_outcome1-final_outcome8 final_outcome1b1-final_outcome1b4;                 aa=0;         Solved = 0;         Denied=0;         Rejected=0;           do i= 1 to 4;             do j=1 to 3;                    if ProblemType(i,j) = 'aa' then aa=aa+ 1;                     if ProblemType (i,j) = 'aa' then                        if final_outcome (i,j) = 'resolved' then Solved = Solved + 1 ;                        else if final_outcome (i,j) = Denied' then Denied=Denied+ 1;                        else if final_outcome (i,j) = 'Rejected' then Rejected=Rejected + 1;                end;         end; run;    This sample code works fine.  But When I specify the following code while using it on original file having 13000 records   array problemType [13000,147]  $; array final_outcome {13000,147) $ ;   SAS goes into infinte loop. It  does not produce any results.   Please help me with this problem. I am new to SAS. ... View more
