the save and loads are done in basic it is clunky but was done that was so that others could modify the basic to suit there storage system i.e USB or other SD card solution, what ever solution you use needs to be able to load / save chunks of memory.

Ah, I didn't think to try pressing BREAK...

Excellent, I've got 32K battery backed RAM 8K-paged at 40-48K (for H4th Forth block filing). I can use that for temporary data.
