Hi there, something like this solve your problem?
data have;
input id wait_time pts_1 pts_2 pts_3;
datalines;
1 12.85 1.67 2 1.5
;
run;
data want;
set have;
array pts pts:;
do over pts;
pts=pts+wait_time;
end;
run;
-unison

The statement
pts+wait_time;
will work for this problem, as stated. But I would NOT recommend it. This is a SAS SUMming statement, which means (1) is will accumulated values over consecutive observations (not a problem here), and (2) will not always produce the same results as
pts=pts+wait_time;
Take a look at the results for observations 3 and 4 below, where there are missing values introduced:
data have;
input id wait_time pts_1 pts_2 pts_3;
datalines;
1 12.85 1.67 2 1.5
2 11.85 1.67 2 1.5
3 10.85 . 2 1.5
4 . 1.67 2 1.5
run;
data want1;
set have;
array pts pts:;
do over pts;
pts+wait_time;
end;
run;
data want2;
set have;
array pts pts:;
do over pts;
pts=pts+wait_time;
end;
run;
Arrays are the recommend approach here.

Hello,
I’m working on a rather large data set that I need to add one value to several hundred other values in the same row.
And example would be:
ID Wait Time Pts 1 Pts 2 Pts 3 etc.
1 12.85 1.67 2 1.5.
Output
14.52 14.85 14.35
There has to be an easier way to do this without manually inputting formulas one by one for each value.
Thanks

I think that you need to walk us through the explicit formula you are using. The input data has 5 values and the output only 3. So which variables are used and how to get that output??
