Not Sure if this is the correct category, but here goes.
I would like to open up certain text files in a folder. I would then like to
change
a particular string to something else. Is there a way to update a record while
reading through the text file, or, can I issue a REPLACE command to the
entire file.

I'd like to avoid reading the file, making the change and outputting to
another file.

Thanks for any advice.
