I thought Andy was talking about source code.

Personally, if I have to rename a method, I search for all senders and fix them with copy&paste. Same for class renames, inst var renames, etc. There just are not that many occurrences, so fixing each one individually is quick, plus I get to verify that the change is indeed what I wanted.

There is a tool to automate a lot of this called the Refactoring Browser, which many developers like, but I don't even have it in my image.

Thanks very much to both of you.

Bert, you are quite right, I was talking about changing strings in source code - sorry, I should have made that clear.

The problem is that we I am dealing with an image where a number of strings have been hard coded into various methods. What I was looking for was a global - source code - search and replace.  Does that exist?  Or, is it possible to FileOut the entire source tree, do a search and replace externally, and then file it in again. I have tried this in the past, but the image never seems to work properly afterwards.  

Clearly, the correct way to solve the problem is to abstract the hard coded text into another object - or maybe a global variable? Perhaps I will just have to bite the bullet.  This would make it far easier for internationalisation etc.  Actually, are there any packages to help with internationalisation?

Cheers
Andy
