Cd doesn't return a value so nothing is output with this example

Interesting ... and there's probably a good reason for that, but I don't know what it is.
Certainly, the behaviour you're seeing doesn't conform to the documentation I get for cd, which begins with:

C:\_32\C>cd /? Displays the name of or changes the current directory. CHDIR [/D] [drive:][path] CHDIR [..] CD [/D] [drive:][path] CD [..] .. Specifies that you want to change to the parent directory. Type CD drive: to display the current directory in the specified drive +. Type CD without parameters to display the current drive and directory. .....
Perhaps you're running in a different shell (I use cmd.exe), or perhaps your cmd.exe shell finds a different 'cd' implementation to run.
To force your cmd.exe shell to use its own implementation, I think you just need to involve a shell metacharacter in the command - eg:
cd <nul
Does that command print out the current directory for you ?

(Admittedly this has nothing to do with the subject you initially raised ... but I find it a little bit interesting.)

    Hi Rob,

    I apologize. My error. I do run cmd.exe and just reran your code example. cd was, indeed, returning a value. However, since the returned value looked exactly like the command prompt only minus the > sign I just didn't realize that it wasn't the command prompt. I'm not generally dense. I don't know what's wrong with me here lately. Anyway, your example was fine. I just messed up reviewing the result. Thank you again for the answer.



    After messing around with the syntax a little I did finally get it to work at the command line. Thanks again Rob.
