Got it, thanks for the reminder
I want to know whether it can be done without relying on third-party tools

Of course it can be done, but the efficiency is obviously not as high as sed
Sometimes don't be so set on using only the commands built into windows
Isn't text processing all about efficiency?
If it's purely for research, then you can write it, but if it's simply to improve the speed of text processing
you might as well consider third-party tools

1 is for processing documents, 2 is for learning. Learn the logical thinking of the experts a bit, and improve my own ability :P
Hope someone can help write pure ms-dos code :)]>
