Word Name	Word Type	Data Stack Signature	Return Stack Signature	Description	Availability
Word Name	Word Type	Data Stack Signature	Return Stack Signature	Description	V1.0	V1.1	V1.2
-->	I	--	--	Loads the next block from the file currently in USE.
BLK	S	-- address	--	Contains the number of the block currently being accessed, or 0 if no block is currently being accessed.
BLK?	S	buffer -- block vdp_addr	--	Returns the disk block stored in the buffer buffer (or 0 if the buffer is empty) and the VDP address vdp_addr of the buffer.
BLOAD	S	block -- nfb	--	Loads a block of raw memory from block storage that has been previously saved with `BSAVE`.
BLOCK	S	block -- vdp_addr	--	Loads block block from the file currently in `USE` into a free buffer.
BSAVE	S	start block -- nb	--	Binary Save - saves a block of memory to the current blocks file.
BUF?	S	block -- buffer vdp_addr	--	Returns the buffer number of block block, and its address in VDP memory as vdp_addr. Returns 0 0 if the block is not in memory.
CLEAN	S	buffer --	--	Sets the status of buffer buffer to clean. Subsequent `FLUSH`es will not flush the buffer to disk.
CLOAD	I	block --	--	Conditionally loads block if the word immediately following `CLOAD` is not found after a dictionary search.
DIRTY	S	buffer --	--	Sets buffer buffer's status to dirty. Subsequent `FLUSH`es will causes the buffer to be written to disk, to the block set with `SETBLK`.
DIRTY?	S	buffer -- flag	--	Returns TRUE if buffer buffer is dirty (i.e.the buffer has changed since being loaded from disk (via BLOCK or LOAD and requires flushing to disk), otherwise returns FALSE.
EMPTY-BUFFERS	S	--	--	Unconditionally sets all buffers to `CLEAN`. Subsequent `FLUSH`es will not write anything to disk.
FLUSH	S	--	--	Flushes all dirty buffers back to their respective block positions on disk. Buffers not marked as dirty are not flushed.
LIST	S	block --	--	Displays block *block* to the screen.
LOAD	S	block --	--	Loads (compiles/executes) block block.
MKBLK	S	size --	--	Creates a block file (used for storing source code and/or data) on the nominated disk, with enough space for `size` screens/blocks of data and sets the new file as the current blocks file.
MKDSK	I	size --	--	Creates a block file with the name file and capacity for size blocks.
SETBLK	S	buffer block --	--	Associates buffer buffer with block block.
THRU	S	start end --	--	Loads blocks starting at block start thru end inclusive.
UPDATE	S	--	--	Marks the last accessed block as dirty.
USE	S	string --	--	Defines the block file to be used. A string should be set up on the stack before calling `USE`.
WHERE	S	-- block	--	Returns the block number of a user-loaded word in the dictionary. Non-existant words return 0.
