Bill,

I you want it checked in, send me a patch and I'll see to it.  With the 
convert stuff, there are some nuances that you may want to be careful 
about.  char and varchar using STRINGBING and NTBSTRINGBIND act 
differently.  One of the unittest programs checks it, you will want to 
make sure it passes.
