Hello Tony Thanks for the heads-up. I'll take a look.

I use it to merge Included code modules so that I can run, debug, and edit them as a unit, then split the modules off back into their components. From there, re-compiling all code allows the entire app to benefit from an individual effort. http://Nebula-RnD.com/freeware/ The utility gets a uniquely stamped backup of every item before every operation to ensure nothing gets lost. WRT your query, it sounds like you want to factor out common code. I'd approach this by writing a utility that scans items for common blocks of text, wrapping those blocks with start/end markers which I use in the Merge/Split. So let's say you have 100 lines that start with label FOO: * do foo. Wrap that as follows: *! START.INCLUDE INC.FOO FOO: * do foo *! END.INCLUDE With all program items marked like that, run the Merge/Split on them and do a split (without a prior merge since you're creating new Includes). You'll get a single INC.FOO item and all other items will then INCLUDE INC.FOO at the right location. This will take some manual effort. You don't really know what blocks to refactor out until you've looked around for common patterns, and you will find a lot of blocks that are close but not quite the same. You could factor out all FOO subroutines into individual items, then delete items that are the same, and modify code which includes that code to use a single Include item. The most benefit comes when you find lots of large common blocks of code. This usually comes in the form of long EQUate lists, Common definitions, blocks of Open statements, and logging and other housekeeping. You may even find value in Includes of Includes. If you do use the Merge/Split freeware, I'd appreciate if you'd pass back any updates you make for this specific purpose. Aside from that more manual approach, check out mvToolbox. It has a ton of features that do all sorts of magical things - for all I know it might have some hidden function to help to refactor out an entire application. Some developers load it to every new site they work on, to organize app code before doing any other work on it. (Yes, that needs to be done properly.) http://www.mvtoolbox.com/index.html Use that link to avoid getting passed off to the awful awful web ring. While marketed via a poor website, mvToolbox is great software which only suffers from having too many features and too much documentation.

Re: [U2] Refactoring Tools
Hi Brian: Built into BDT from Rocket Software is a re-factor option. I have used that option a few times in testing and found it to be of limited value, because there is no way to get all of the code locally. You must have the code locally to use re-factoring. I have re-factored code in Eclipse using the Java Editor. I found that does a fairly good job. In our XLr8Editor I have not put in re-factoring because the Eclipse global search and replace does an adequate job for changing the source. I generally like to see all of the code and make sure it it what needs to be changed. I can copy and paste source to you local work space fairly easily which solves the local problem for Eclipse.

Re: [U2] Refactoring Tools
Jeff - Exactly :) I mean refactoring as in restructuring old code to make it more testable and consistent. You find these tools for .NET, java and other languages though there the model is different because of the OO nature. Universe code doesn't decompose down the same way but I was just wondering whether anyone had built some assisting tools before I have to start designing and building some. Example, an slice through a program that mixes UI and business logic to rip out the useful guts into external subroutines for unit testing whilst preserving the overall logic safely. Which means the tool needs at least a rudimentary understanding of code syntax and scope rather than just stripping lines out. (e.g. this block sets a local variable as a by-product, that also just happens to be used 5,000 lines later on in a GoSub so it needs to be surfaced if the block is externalized - that kind of stuff that could easily get lost). I've written plenty of code analysis software but not specifically for this.
