Pretty sure you have figured that out in 5 days but you simply forgot to read your data INTO DM

proc iml;

use kaplan;

read all var{time survival survival1} into DM;

close;

Your DO loop will also crash as you will eventually try to get time[dim(DM)+1] which is out of bounds. I don't know if it was intended that the time used differed from the survival columns used so I'll let you figure out how you change it, either change SS= and loop from 1 to dim(dm)-1 or change TT=
