Actually, the problem goes a bit deeper, it is the xt returned by ' and FIND. This xt is the problem, it does not allow straight-forward access to its interpretation and compilation semantics. Especially since the immediate flag is lost, the xt does not know if it is immediate or not. Smart COMPILE, fixes that. But then, it somewhat changes the meaning of COMPILE,. > Therefore, simply standardise a new word, something like 'I (which > means 'tick the *interpretation* behaviour/address/cfa/whatever' of > the word.

The dual-token approach with ' for interpretation semantics and COMP' for compilation semantics has already been tried out, it's Anton's approach at solving the problem; it is in Gforth since quite some time. It wasn't a full solution, since it required adding another type, the "name token", which still had all relevant informations, and converting that to an xt, these informations were lost. -- Bernd Paysan "If you want it done right, you have to do it yourself" http://bernd-paysan.de/
