coincidence ...
the first 2 lines contain the name of the program and the name of the
author.
When you rename to bat the first line is echoed to the screen by
command.com
idirmagic is no valid command, so an errormessage us issued, and
command.com contiunes.
Michael is echoed, and executed, again no valid command.
After that strange non ascii chars appear, and command.com aborts.
Try it with a exe file.
There the effect is more noticeable !

no
part of command.com ran (and tried to interpret a part of your file)

NO !!!
it did come from command.com
try to add a @ as the first char of your bat.
it will not echo the name of the program, but the error message will
remain.
Simply because the @ means that command.com should not echo back the
command.
