Syntax nano -D <script name>
Not to spoil the fun, but as far as I know above option will only make the text for the menu options and the top bar bold (bright white) with a black background instead of the black text on a gray background:
[root@smetest ~]# nano --help | grep "\-D"
-D --boldtext Use bold instead of reverse video text
[root@smetest ~]#
It has nothing to do with writing CMD/BAT files. You can use nano without the -D option for that as well, or pico or vi for that matter.
