I always start writing an awk script thinking it's simple, but find myself baffled by the strange result.. This time again..
I have a file list.txt with lines below (reduced for test. The line following 'Preview Abstract' is the abstract, and the following 'View details' is the paper title.)

and I want to get a file like this (in "title ## abstract" format).
From Language to Goals: Inverse Reinforcement Learning for Vision-Based Instruction Following ## This is the first paper's abstract.
A Study on Overfitting in Deep Reinforcement Learning ## This is the second paper's abstract.
Ask the Right Questions: Active Question Reformulation with Reinforcement Learning ## This is the third papers's abstract.
So I wrote this awk script (paper.awk). (uses keyword to keep title and abstrct lines and print them in the wanted format after getting the paper title)
print_res == 1 {print title " ## " abs; print_res = 0}
next_abs == 1 {abs = $0; next_abs = 0}
next_title == 1 {title = $0; next_title = 0; print_res = 1}
/Preview Abstract/{next_abs = 1}
/View details/{next_title = 1}
When I run awk -f paper.awk list.txt, I get
## This is the first paper's abstract.cement Learning for Vision-Based Instruction Following
## This is the second paper's abstract.ment Learning
## This is the third papers's abstract. Reformulation with Reinforcement Learning
Somehow the paper titles are overwritten with the ' ## abstract" string. What's wrong?
