DosItHelp is injecting a command into the string replacement processing.
For a fascinating example of injecting a command into the string replacement process - see the :format function. That function blew me away when I saw it in action.
It helps to run with ECHO ON if you want to understand how it works.The mechanism of inserting content with ECHO in the :format command is basically the same as truncating the content with REM in DosItHelp's :findstr function.

@jeb
Thanks for killing my code!
You do it so well 
Your idea looks promising though.
I'm intrigued by the clever trick amel27 used in How to replace "=","*", ":" in a variable. It seems like it could be useful here. If we replaced occurences of search string within target with =, we would only need to apply his trick once to split the string. But three things have held me back from trying this:
- It is difficult to execute the replace if the search string contains =
- There might already be an = in the target string - it would have to be replaced before split (again difficult) and restored after (simple)
- The amount of code it would require. I haven't yet traced through each step of amel27's code to see why it was necessary. It's more complicated than I would have thought.
But if there were ever a situation where we could know that = was not aready present, it seems like it could be useful.
