One idea to switch the elements is the following...
Code:
Loop, read, %A_ScriptDir%\InputTest.txt
{
++CountIndex ;Var that counts the lines
If Not Mod(CountIndex, 2) ;If the line is even: 2, 4, 6 etc.
;write in the var output the contents of the even line and the odd line (switched)
Output = %Output%%A_LoopReadLine%`n%ReadLine%`n
Else
ReadLine = %A_LoopReadLine% ;If the line is odd: 1, 3, 5 etc. save it contents in the var Readline
}
;Insert the next two lines, when in case of an odd number of elements the last one should copied
If Mod(CountIndex, 2)
Output = %Output%%ReadLine%`n
FileAppend, %Output%, %A_ScriptDir%\OutputTest.txt
Here some explanation:
Mod(CountIndex, 2) retrieves 0 or 1 if the line is even or odd.
When the row number is divided by 2, the remainder is always 0 when it's even or 1 when it's odd. Then comes a trick: The value 1 stands for true and 0 for false in the if statement.
