So the real problem here appears to be that the OS 9 bootscript is using the rstack in order to store temporary variables. Since the Forth version of interpret is based in a loop which looks up each word in turn and then runs execute, the manipulation of the rstack with r> confuses the loop causing it to drop out early.
You should use a separate (software) stack for rstack things in interpret mode (this is what other OF implementations do).
Okay. Don't suppose you could point me to some examples on how to do this?
