Batch is essentially the language that MS-DOS (text based OS in Windows, nowadays separate) speaks to interact with the user. A batch file is essentially just a file that contains commands to be executed so you don't have to type them in by hand. This batch file can also create variables, just like you could do manually in MS-DOS. And it can create, write and delete files. With all that in mind, we can create a file that contains code of a different language (Visual Basic) that lets us actually create this message, a so-called dialog box. The title and content can be stored in variables or directly. Either way, your computer has in memory. If we now run the batch file (or batch job, as it is called internally), the computer basically enters all that code into the command line by itself. The result is the text box as desired. I'll cook something up in a bit.
