If all
arguments have missing values, then the result is a missing value.
Otherwise, the result is the sum of the absolute values of the non-missing
values.

Examples

Example 1: Calculating the Sum of Absolute Values

The following
example returns the sum of the absolute values of the non-missing
arguments.

data _null_;
x=sumabs(1,.,-2,0,3,.q,-4);
put x=;
run;

SAS writes
the following output to the log:

x=10

Example 2: Calculating the Sum of Absolute Values When You Use a Variable
List

The following
example uses a variable list and returns the sum of the absolute value
of the non-missing arguments.

data _null_;
x1 = 1;
x2 = 3;
x3 = 4;
x4 = 3;
x5 = 1;
x = sumabs(of x1-x5);
put x=;
run;
