I was looking at an old IBA program by BizzyPak, and have been trying to convert it, but I have got stuck on Dereferencing. I admit, it's a Dark Art to me! If anyone can sort it, it would be a great help to me in understanding how Typecasting and Dereferencing work

Hi Brian,
I took a quick look at the Retriever, not going to pretend I understand it either but node hasn't been initialized has it?

Well, this is as far as I have got. It compiles, but after selecting a keyword and pressing Begin Search, it goes off into Never-Never Land!

I think it's because of this:
node = nodes.nxt
WHILE node <> NULL
node = nodes.nxt
ENDWHILE
nodes.nxt is a pointer to nothing the value is probably zero and the condition is never met.
