The data file donation dat is in the STA $3024$ folder. The first $10$ observations are:

$120265...25$

$12026715151515$

$12026920202020$

$12027020105.$

$12027120202020$

$12027515151515$

$12066025252525$

The following variables should be read in using list style input:

$Q1,Q2,Q3,$ and Q $4$ are the quarterly donations from each person.

Create a SAS data set containing the ID$,$ Q$1,$ Q$2,$ Q$3,$ Q$4$ and two new variables:

The total of the donations for each person.

Use SAS functions to calculate the new variables.
