Hank,

When installing TQSL-108.EXE you get TQSLLIB.DLL. I didn't analyze yet but I
guess the API calls could be made through that DLL.

Then you got TQSLLIB-1.3.TAR.GZ which includes a lot of C++ source code and
documentation. Maybe it could be useable.

I did not yet really have time to look through it but I think it would a
starting point for available functions and descriptions.
