I'm using SAS 9.4 full edition and am trying to add up money within an array. The variable MONEY below is coded as a numeric variable with format dollar15.2. I think the if statement is the problem because I keep getting 0 as the answer. I don't know how to code that line which adds up all the amounts in the MONEY array for a given row.
Thanks for the help!
array MONEY  MONEY1-MONEY50; TotalCost=0; do i= 1 to 50; if MONEY [i]=' ' then TotalCost + ' '; end; format TotalCost dollar15.2;

1. Space is missing for character variables not numeric. Use the MISSING() function for both numeric and character variables interchangeably.
2. The SUM operator (+) assigns the results to missing if any of the values are missing.
3. The SUM() function will treat missing as 0 or non existent.
4. The SUM() function can take a list of variables or an array reference.
All of this can be found in the relevant documentation.
data demo; a=0; b=.; x = a+b; y = sum(a, b); run; proc print data=demo;run;
