Please construct a simple example of what you are trying to do to clarify your problem.
You probably do not need to include all 24 fields or more than two or three paths per example row. Also for purpose of sharing your example it will be easier to use | or some other character instead of LineFeed to delimit the paths:
data have;
infile cards dsd truncover ;
input v1 :$10. v2 v3 paths :$200. ;
cards;
A,1,2,/one|/two
B,2,3,/three|/four
;
Then show what output you want from this example.
How is it that you know something new is added? Is one of the fields a date or datetime value?
