The code should refer to a vector of vector of string, but the string part keeps being removed from the post. How do I post so the code stays the way I want?

But here I am reading from a file format which someone else (probably at Microsoft many years ago) invented.

*edit*  Also, using platform-specific types like "long" and "short" is a bad<br />
idea if you expect to match the Microsoft definitions.
