!Urgent Reading / Writing to specific line in a text box.

I really needed the answer to this a few days ago.

Ok lets say I have a text box with the following content.

Color =Blue
Width =18
Name =Smith
Age =13

How can I read what comes after the = sign on a specific line into another text box.

ex. line 3 is "Name =Smith" and the output in a textbox would be "Smith"

Also on the other end of this, how can I write to a specific line in a textbox, and I would like it to replace the line currently there.

ex. I want line 2 to read "Width =19" then the textbox would look like this.

Color =Blue
Width =19
Name =Smith
Age =13


If possible please explain the steps as much as possible.

Thanks for any help anyone can give, it is really appreciated cause I'm in a such a jam.

the split function will help you get the parts of the line separated

If you are still looking tomorrow... let me know. I have some examples at work that are exactly what you are looking for.
