Local $file = "TEST.log"
FileOpen($file, 0)

For $i = _FileCountLines($file) - $TTLPax to _FileCountLines($file)
    $line = FileReadLine($file, $i)
    Global $TktNo = StringMid($line, 8, 13) ; reads 13 characters from $Line starting from the 8th character
    msgbox(0,'',$TktNo) ; This is just for me to debug
        For $NoOfPax = 1 to 2
            local $TTLSeg = 2 
            msgbox(0,'',$TTLSeg)
            msgbox(0,'',"7ABC"& $TktNo &"'N"& $NoOfPax &".1'C1,2'S1,2'B") ; This makes 7ABC1234567890123'N1.1'C1,2'S1,2'B 
                                                                          ;But in the next loop I want the value to be 7ABC1234567890333'N2.1'C1,2'S1,2'B

I am reading a file with last 5 lines as above. I want to be able to loop through and pick the values as follows

1- Pick 1234567890123

2- Use it to build a format with N1.1

3- Pick 1234567890333

2- Use it to build a format with N2.1

Need help with the loop. Thank You
