This is no permanent directory, either, but the very same you have in your 
own programs. While a program is running, let that be a small utility, an 
complex application or a command interpreter, there is a current directory 
it keeps. Whenever you issue that CD command, you change the current 
directory of *that copy* of CMD.EXE, nothing else. If you have several DOS 
prompts running, they will not influence each other and as soon as you exit 
any of them, the current directory vanishes with the program. There is 
simply no way to solve this otherwise in a multitasking operating system.

But you could tell us why you want to modify the current directory of a 
program from another one (as far as I can tell, this is what you actually 
aim to do). We might come up with an alternative solution.
