how to run a .bat or .cmd file from bash prompt

["J.V." <jvsrvcs at gmail dot com>]

To run a .bat or .cmd file, I can do this:
    $cmd

    C:>mybat.bat or C:\>mycmd.cmd

In other words, I have to type two commands (one to get to the shell, 
and another to run the .bat or .cmd file).

What I want is to write a shell script (bash), that will cd to a 
directory, enter the dos cmd prompt and execute a .bat file and then 
return to my bash shell.

I do not know if this is possible, have tried many things, but nothing 
works.

thanks

J.V.
