stopping a batch file when an error occurs?

[yawnmoth]

Say I have the following *.cmd file:

@echo off

cd some_directory
cd ..

If I run it and some_directory exists, nothing will happen - I'll be
in the same directory as before. If, however, some_directory doesn't
exist, it'll take me back to the parent directory.

My question is.. how can I change this behavior? How can I make it
so that if some_directory doesn't exist, it doesn't do "cd .."? Maybe
I could do some sort of if statement and do the "cd .." conditionally?

IF Exist C:\some_directory (
