When a word modifies the buffer, it sets the buffer as dirty
|
|
by calling BLK!!. BLK@ checks, before it reads its buffer,
|
|
whether the current buffer is dirty and implicitly calls BLK!
|
|
when it is.
|
|
|
|
The index of the block currently in memory is kept in BLK>.
|
|
|
|
Many blocks contain code. That code can be interpreted through
|
|
LOAD. Programs stored in blocks frequently have "loader blocks"
|
|
that take care of loading all blocks relevant to the program.
|

|
|
Blocks spanning multiple disks are tricky. If your media isn't
|
|
large enough to hold all Collapse OS blocks in one unit, you'll
|
|
have to make it span multiple disks. Block reference in
|
|
informational texts aren't a problem: When you swap your disk,
|
|
you mentally adjust the block number you fetch. (cont.)
