I need to write an external for LiveCode in C++, but I doubt my ability to do it.

Hi Jonathan,

I would start by seeing if your LC code can be optimized so the time it 
takes per screen is acceptable. There are many small changes a person 
can sometimes make to code that causes dramatic speed increases.

Or is the bulk of the time spent in areas LC can't address natively? 
Maybe that's why you want to go toward an external.

Thanks -
