I want to match the ^ in the previous line H or L operation and also the Corresponding pin number which is at the top The output file should be like this

Output file 

 pattern offset pin_num
 scan1   2965    p13        H
 scan2   2200    p22        H
 scan3   1100    p22        L
 scan4   1500    p13        H 
 scan5   2800    p22        H
