adding money in an array statement

lmyers2 — Thu, 07 Dec 2017 01:47:35 GMT

Hello,

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!

Best

Laura

array MONEY [50] MONEY1-MONEY50;
TotalCost=0;
do i= 1 to 50;
if MONEY [i]=' ' then TotalCost + ' ';
end;

format TotalCost dollar15.2;

This doesn't need a do loop.Instead you can:

array money {50} money1-money50;
totalcost=sum(of money{*});

Some pointers:

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;
