You need to create a script write to a text document

When in 2007 I created a script write to a file , now it does not work.
Now need a new script to perform the same task, to write to the txt file information that will be used on the website for AutoCorrect.

In the text file information is stored in this form :
----------------------------------------------
%city% ;;; city
%save% ;;; save
%phone% ;;; Phone
----------------------------------------------

The first column are the variables for avtosalony
the second column words which should appear instead of variables

The Annex attached a picture of the interface.
