Code:
I only put the comments

That's why its important to post real data, and lots of it.

I still have some problem to understand your logic.
Code:
CAR        2300 2455
MOTOR  2455 4000
BIKE        4000 2347

CAR I do understand.
MOTOR why not 1000-4000
BIKE 2345 2347 ??

Edit:
Something like this:
Code:
awk 'NR==1 {top=$1} {t2=t1;s2=s1;t1=$1;s1=$2} NR!=1&&s2!=s1 {print s2,top,t2;top=$1} END {print s2,top,t1}'
CAR 2300 2455
MOTOR 1000 4000
BIKE 2345 2347

Hello Jotne,
Thanks for helping me out, I will post the real data as soon as I
can.

The First number of CAR is 2300
The Last Row of CAR is: 2455
2300 is the TOP of Lithology
2455 is the BASE of Lithology
The BASE number of 2455 needs to be used for the next Row of
MOTOR 2455 The BASE of previous becomes the TOP.

The examples have helped me out, thanks again.
Charlie
