I spent about 2 hours and finally almost got the script running OK (it was too late in the afternoon). Here are two notes about the work.

By default, VIM has match feature. For example, if you edit a .c file, press ‘%’ when you are at {, [, or ( char, you will see the corresponding }, ], or ) is highlighted, and your cursor will jump back the forth.
