SAS Equivalent of COUNTIF across a row of data

[gazp23]

Hi

I'm trying to create a new column called "MONTH_COUNT", whcih will look across a row of data and count how many values are greater than 0.  The full table has around 9,000 rows and 40 rows (monthly totals and varioius flags to categorise customers).

My current data set looks like-

Customer MAR-17 APR-17 MAY-17

A                    0           0           100

B                    10           10          10

C                    50         70          75

Desired output-

Customer MONTH_COUNT MAR-17 APR-17 MAY-17

A                        1                    0            0           100

B                        3                  10           10          10

C                        3                  50          70           75

Thanks in advance!

Well, its by using arrays.  The longer version is (and this is not tested as you have not provided test data in the form of a datastep so I nothing to work with nor knowledge of structure):

data want;
  set have;
  array values{3} mar17 apr17 may17;
  do i=1 to 3;
    if values{i} > 0 then month_count=sum(month_count,1);
  end;
run;
