Re: [Amforth-devel] Heap pointer in EEPROM, Why?

hi,

It is the pointer to the first unused ram address. There
may be words in the dictionary that uses ram below it and they
depend on the absolute address.

No, the content of the RAM is lost, but not it's structure.

The words that allocated RAM will use it again at the same addresses
(that those words need to store somewhere, e.g. as a variable entry
in the dictonary).
