It doesn't have to be that way. You just need to be clear about the "surfaces" where the code interfaces to the next bit of code. I have had no problem moving applications across several platforms but I have known the interfacing surfaces I am dealing with to a high level of detail. The ANS standard deals with some of the notions but you have to be aware of what the supplied Standard Forth's are giving you and when there are implementation dependent differences that you will need to adjust for. Start to think about where you might put in a compatibility layer. -- ******************************************************************** Paul E. Bennett...............
