Find unique values from a comma separated variables using a batch file.

Batch files are text files containing a script of commands that are executed by the command interpreter on DOS, OS/2 and Windows systems. Most commonly, they are used to perform a series of functions that are repeated -- copying a set of files created daily with one step, for example.
