Blocks allow for a simple storage subsystem. In the smaller ilo
|
|
and napia based systems, they are mandatory and are the primary
|
|
means of data and code storage
|
|
|
|
Under RetroForth/nga, this is optional, but is enabled by
|
|
default.

The exposed word set is compact:

|
|
block:set-file (s-)
|
|
block:read (na-)
|
|
block:write (na-)
