For the romable feature:

We need to save the ram area (there might be initialized variables,
and code-fields...) into rom and copy it back at system startup.

[THEN]

\ save ram area

>rom
unlock sramdp @ lock		constant ram-start
unlock ramdp @ sramdp @ - lock	constant ram-len
variable ram-origin
ram-start ram-origin ram-len unlock tcmove lock 
ram-len allot align
