Nadya,
Once the file is opened, you can search for the required function and use the position in the file to go to the correct function. You may have to set a pattern of characters that determines when a function starts. For example the lines before and after a function might always be:

*!*START*!*
Function Func1()

Return lRetVal
*!*END*!*  

You can loop through the PRG file finding each function and matching the name with a variable passed in with the Edit button easily.
