Transfer of control to command prompt

[NotAGeek]

Does anybody know if there is anyway to transfer control to a new command prompt from the existing one?
for example I am trying to write a batch file which will open up a new command prompt and then all the things I want to do would be done on new command prompt and not the old one.

for eg.
@ECHO OFF
START C:\Windows\System32\cmd
cd C:\SomeFolder
pause
exit

above commands opens a new command prompt but let's say if I want to change directory on that new command prompt how do I do it?
in the case above it will change directory in the first command prompt. not the one that is opened by this batch file

CALL opens a new command shell session, but I'm not sure if you can switch about between spawned sessions, I think you can only run a second batch or executable in the second session and then close it and resume processing the parent batch file.
