	I don't know how your system handles libraries, but for all languages
I've seen, the library pointer must go in a global variable of a specified
name so the interface routine (for OpenDiskFont) can find it.  How else is
the interface code for OpenDiskFont supposed to know that there is a valid
DiskFont library pointer around?  You don't pass it to the code, so it must
be looking for a global somewhere.  Read your compiler documentation for
interfacing with library routines.

	Note:  the same problem applies to the other libraries, unless the
system happens to have opened them already (like C startups open dos.library
for you).
