Thanks, highend .   That did better than I was doing.  I think I am ready to admit that I need a complete form template of some kind.  There are quite a few of these input fields, some need to have character count limits, some need to be set for numbers only.  We have used this specific setup script for some time and it works so well I hate to give it up.  But it is hard to explain how it works for new hires.
There are hundreds of 'forms programs' out there including MS Access and even Excel.  There are probably only 10 variables that have to be input and then another 4 or 5 that are created within the script.  It would be nice if I could get all this to display on the screen at the same time just like a filled-in form.
This would let me catch any errors before the project gets created with erroneous input.  Clicking the "GO" button at the bottom would accept the data fields and continue the creation and the displayed form could be saved as a filled-in template.  It might come in handy to be able to open that same form at a later date to see what was done.   
In addition, since these things are created sequentially, opening the last form would automatically fill in the same data fields and I could just change the ones that needed it.  A couple of us who use this in the IT department have played around with different options but since the script was written in a batch script the only thing I can think of for making a nice front end form would be to use HTA to make it.  Or maybe VBS.  Powershell is a pain since Windows restricts it by default
I figured there might even be something already on the Board from long ago but maybe I am searching with the wrong terms

i think I'm getting lost in the iterations which is normal for me :(
i started out trying Find And Replace" (FAR) but never got it to work properly, perhaps due to the unusual characters.
I end up getting a working script using the Set command but hit problems when i tried to run it recursively over all 100+ text files in the folder while keeping the file names unchanged.

Each file is contains a single string repainting a URL and there are no spaces in the string.  The domain portion of each has changed and tht is the only part i need to modify  -  replace the section that says "domain1.com" with "domain2.com" ,change nothing else and keep the original filename.

This has to be done to over a hundred urls stored as named text files in a master folder.

So far this is what i got:


This works on a filename by filename basis but requires temporarily renaming the files while they are processed.   I feel sure there is a way to walk the directory recursively and keep the filenames intact during the modification.

As written, the code above requires an infile and an outfile a bunch of renaming and is far more 'work" than should be needed.

I bet 4WD will have what I need right at hand if he is on line.  :).   
I would like for the result to be flexible enough to save the code for use on future projects where i might need to do something similar.

Thanks
