Kurt,
BTW you don't need to use actual keys there. A TV requires basically 3 properties (nodeID, parentID and nodeText. You can create a cursor for yourself that have those fields and the rest of the fields are for yourself. So you can do something like this:

create cursor myTV (nodeID c(10), parentID c(10), nodeText c(50), myTableNAme c(10), myKey i)

nodeid and parentid might then simply be values like sys(2015), you use it to locate the row in this cursor and get target table and PK from there if you want.
