Simple script file reader/writer

[ficofico]

Hy guys, I've found this amazing tool and forum ....

I've a problem that need to solve

I've an input box

GUICtrlCreateGroup("Luminosità", 10, 200, 120, 40)

$luminosita = GUICtrlCreateInput("", 12, 220, 100, 20, $ES_NUMBER)

and a button

$provabutton = GUICtrlCreateButton("prova", 50, 300, 80, 30)

I want that ,on lunch executable , input read from a txt file , and changing the input box with another value and pressing the button, the txt file change

I don't know how do this, and with help I have found "write in a line" or other, but it's possible to write "text", not variables

In the text file I need to read and put only a floating number, not strange arrays.

It's possible to do this? Very thanks at all...
