Collapse OS file system
|
||||
|
||||
This is a Forth-style filesystems which is very simple. It is a
|
||||
list of 1024 bytes block, organised in 16 lines of 64 columns
|
||||
each. You refer to blocks by numbers. You show them with LIST.
|
||||
You interpret them with LOAD.
|
||||
|
||||
Conventions: When you see "(cont.)" at the bottom right of a
|
||||
block, it means that the next block continues the same kind of
|
||||
contents. This of course only work for informational text.
|
||||
|
||||
Block numbers are abbreviated with prefix "B". "BX" means
|
||||
"block X".
|
||||
|
||||
The master index of this filesystem is at B1.
