- 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 multipls 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.)
