NOT FINALIZED!

The functions in this section exist to support new features of PicoDOS 2.0 and should be considered experimental. Even with the woefully inadequate documentation that currently exists, these may be useful to more complex applications. Be warned that unlike the finalized BIOS and PicoDOS functions, these functions are subject to much change, and you should not use them if you are not prepared to recode your projects as the functions mature.
