After much wailing and gnashing of teeth, I finally built
my first QuickBASIC Library!  I found out two things I want
to mention that others might be able to learn from or help
me learn more about.

I beat my head against the wall for more hours than I
care to admit trying to get my first library to compile.
The problem, which seemed strange to me was:
    One of my half a dozen SUBs "INP-LIB.BAS" would not
    compile.  The compiler kept barfing and telling me that
    it couldn't find LIB.LIB.  I went nuts trying to figure
    that one out until I somehow realized that the compiler
    had truncated "INP-LIB.BAS" to "LIB.BAS" (or "LIB.LIB).
    As soon as I removed the hyphen, it worked fine.
    I presume the "rule" I violated was "Library file names
    must not have imbedded hyphens.", but I never knew or
    read of that rule.

The second thing I found strange was that variables kept
going to zero.  I discovered that:

SUB GetInteger(x%, y%, digits%)
.
LOCATE x, y

works fine in the environment, works fine compiled, but
won't work in a library.  When I went back and put the
percent signs in (LOCATE x%, y%), everything worked fine.
