The changes that you have mentioned mean:
(1) Only a zero after a 1 is considered the
point of relapse except
(2) When all values subsequent to a 1 are
missing in which case RELTIME will be 1.
Count the number of missing values (MISSCNT) after the position of the first
occurrence of 1 (FOUNDAT). After the algorithm completes its search of the
array and assigns RELTIME, if FOUNDAT + MISSCNT = DIM(T) then we know that
all values are missing subsequent to a 1 and RELTIME is reset to 1.
Try the following minimal changes and see if this is what you want. I am
still not clear about ID=3.

This is exactly what I want. ID=3 is exactly should be exactly as you
specified, no event, and replase time=0.
Thank you soooooo much, Venky, you are great!
