Question : ChDir that chooses a directory in the same parent directory as the current one

How do I write a ChDir code that says in effect:  One directory above the current directory, you will find a directory named  "NEW CODES". Choose that directory.

I used to know this but I can't remember.

Thanks,
John

Answer : ChDir that chooses a directory in the same parent directory as the current one

To get to NEW CODES try

ChDir "..\NEW CODES\"
