Simple VBA Macro for Syntax Highlight

[PapoAnaya]

Hi:



I wrote the following small macro for syntax highlight.  It's very basic, but demonstrates how newLISP can be used when you are not in the mood of coding a lot of VBA code for mundane things like that. (I guess I could've used VBA string search routines, but I wanted to try it out anyway. :)
