Introduction

MODRES is a memory resident version of MODPLAY, which can be called by your
own applications using interupt 2F (the multiplex interrupt). The process
number is 82 (hex) and there are six subfunctions - 20 to 23 (hex) are
available with all versions, while 24 and 27 are only available with the
newer versions. Once you have run MODRES, it will remain installed in memory
and can be used by any applications until you remove it from memory with the
-D option, or reboot your computer.

The information provided here comes from my own experimentation with MODRES,
and is not the official documentation. I believe that documentation will be
provided by Mark Cox with a later version (if he hasn't already).
