Write to text file line nummer

Hi,
I've found this function:


No I've the question if it's possible to join instead only a word a complet file with the other file.

Push "$INSTDIR\file1.txt ;Join this file
Push 24;in line 24
Push "$INSTDIR\file2.txt" ;with this file
Call WriteToFileLine

Thank you 🙂

I know File Join but unfortunately (as far I know) I can't define with this a line.
