QB64 equivalent of functions in qbextend.exe for QBasic Games and More! book?

[madscijr]

I came into this book (no floppy disk) which was discussed here last year
https://www.qb64.org/forum/index.php?topic=2433.0

and evidently the program listings all depend on this "qbextend.exe" program,
which I neither have nor do I expect it to work in Windows 10,
for common functions such as keyboard & mouse input and file I/O.

In the above thread, I think they concluded that it should run under DOSBOX
and some version of QBASIC or QuickBasic, provided they have the "qbextend.exe" program.

However, being that QB64 has some nice built-in functions for key/mouse/file I/O,
getting these programs running on a modern PC under QB64 shouldn't be too hard,
assuming the TSR "commands" can be replicated in a library, right?

Any thoughts on this before I dive in and attempt it? Has anyone done this already,
so I (and anyone else who might want to make use of this book) don't have to reinvent the wheel?

Thanks in advance...
