Modify txt file [message #85039]

Hi,
I've pretty much read text files pretty often, but haven't manage to modify a text file in a fast way...
Here is the thing. Consider a text file like this:
parameter1 = 5
parameter3 = 2
parameter2 = 8
parameter7 = 23

I would like to change a line 3 to:
parameter2 = 9

Is there a quick way to do this? At the moment I'm reading the file and storing it in an string array, modifying the selected string and rewriting the whole file. Alternatively, I could write in parallel to another file and then do renaming. But I thought that there should be a smarter way using OPENU, but this way I insert a line and not substitute it... or?

Regards,
Helder
