* I have two batch file x.bat and y.bat.
* I m calling y.bat from x.bat.
* File y.bat sets an env variable like:
set ABC=
* Restriction is I cant change this Y.bat file but I want my variable "ABC" to be set as something else.
* How can I set "ABC" in X.bat so that it is not overriden by y.bat file set command.
