-DESCRIPTION	The RB09 fixed head disk has 8,000 64-word
-	blocks on each of its two surfaces. Unix uses
-	the second surface (physical blocks 8,000 to
-	15,999) and numbers them from logical block 0 to
-	logical block 7,999. The following discussion
-	refers to logical blocks.
-.sp
-	The Unix filesystem is divided into 8,000 blocks
-	of 64 words per block. Block 0 is the "sysdata"
-	block. The first word points to the first block
-	of the free-storage map. Each block in the
-	free-storage map is structured as follows: the
-	first word is the block number of the next block
-	in the free-storage map, or zero if this is the
-	end of the free-storage map. The next nine words
-	hold free block numbers, or zero (no block
-	number).
-.sp
-	Block 1 on the filesystem is unused. (?)
-.sp
-	I-numbers begin at 1, and the storage for
-	i-nodes begins at block 2. Blocks 2 to 711
-	contain the i-nodes, with five consecutive
-	i-nodes per block. Certain i-nodes are reserved
-	for special files, directories and devices:
-.sp
-		1	The core file written by "sys save" or a
-			bad system call
-		2	The "dd" directory directory
-		3	The "system" directory
-		6	The "ttyin" special file
-		7	The "keyboard" (graphic-2) special file
-		8	The "pptin" (paper tape reader) special
-			file
-		10	The "ttyout" special file
-		11	The "display" (graphic-2) special file
-		12	The "pptout" (paper tape punch) special
-			file
-.sp
-	There is only one file system which is always
-	mounted; it resides on the RB disk. This device
-	is also used for swapping. The swap areas are at
-	the high blocks on this device: blocks 6,400 to
-	7,999. These blocks do not appear in the free
-	list.
-.sp
-	Each i-node represents one file. The format of
-	an i-node is as follows, where the left column
-	represents the offset in words from the
-	beginning of the i-node:
-.sp
-		0	flags (see below)
-		1	first indirect block or contents block
-		...
-		7	seventh indirect block or contents block
-		8	user ID of owner
-		9	link count
-		10	size in words
-		11	unique value assigned at creation
-.sp
-	The flags are as follows:
-.sp
-		400000   i-node is allocated
-		200000   large file
-		??????   allocated bit (always on)
-		000040   special file

-		000004   write, owner
-		000002   read, non-owner
-		000001   write, non-owner
-.sp
-	The allocated bit (flag ??????) is believed even
-	if the i-node map says the i-node is free; thus
-	corruption of the map may cause i-nodes to
-	become unallocatable, but will not cause active
-	nodes to be reused.
-.sp
-	Word number n of a file is accessed as follows:
-	n is divided by 64 to find its logical block
-	number (say b) in the file. If the file is small
-	(flag 200000 is 0), then b must be less than 7,
-	and the physical block number corresponding to b
-	is the bth entry in the address portion of the
-	i-node.
-.sp
-	If the file is large, b is divided by 64 to
-	yield a number which must be less than 8 (or
-	the file is too large for UNIX to handle).
-	The corresponding slot in the i-node address
-	portion gives the physical block number of an
-	indirect block. The residue mod 64 gives a
-	word offset in the indirect block, and the
-	word found there is the physical address of
-	the block corresponding to b.
-.sp
-	If block b in a file exists, it is not necessary
-	that all blocks less than b exist. A zero block
-	number either in the address words of the i-node
-	or in an indirect block indicates that the
-	corresponding block has never been allocated.

+It's strongly believed that cas is a "character assembler".  The input
+describes character shapes, and the output is data for GRAPHICS-2.
+
+
+CAS INPUT SYNTAX
+================
+
+: means record following string as a label.
+
+x means following moves are invisible.
+
+v means following moves are visible.
+
+r means end, output label=x-b+number.
+
+All other commands are character pairs denoting y,x coordinates in a
+14x16 character raster.  Draw a line to that coordinate.  Vertical
+coordinates are a-p, and horizontal are a-n.  aa is upper left and pn
+is lower right.  Characters reside on the base line from ma to mn
+(characters like p and q descend below this line).  All characters end
+with a "x mn r" sequence to move to the beginning of the next character.
+
+
+CAS OUTPUT
+==========
+
+The output for each character is:
+
+The label x:
+
+18-bit octal words.  Each word is three 6-bit incremental moves.
+Each incremental move consists of three fields: a 2 bit distance field,
+a 1 bit visibility field, a 3 bit direction field.
+
+If the visibility field is a 0 nothing is drawn, if it is a 1 a line is
+drawn.  The distance field + 1 denotes how many pixels to move in a certain
+direction.  The 2 bit direction field is limited to values in the range 0..3,
+but by adding 1, the actual distances denoted are in the range 1..4.
+The 3 bit direction field with values in the range 0..7 is to be interpreted
+according to this diagram and table:
+
+            y
+            ^			value	direction
+        7   0   1       	-----	---------
+            |           	0	up
+            |           	1	up right
+            |           	2	right
+	6---+---2>x		3	down right
+            |           	4	down
+            |           	5	down left
+            |           	6	left
+        5   4   3               7	up left
+
+
+label=x-b+number.  Number is 01, six bits saying how many moves, and
+10 zeroes.
+
+
+EXAMPLE
+=======
+
+Input:
+
+   :lbk
+   x
+   ai
+   v
+   af
+   mf
+   mj
+   x
+   mn
+   r
+
+This character is labeled "lbk" (left bracket).  Move invisibly to
+"ai" near upper right.  Draw line left to "af".  Draw down to "mf".
+Draw right to "mj".  Invisibly move to "mn" beyond lower right.  End.
+
+This can be interpreted in a grid starting a location ma (row m, column a)
+denoted by a 0, and each succeeding move indicated by an increasing number:
+
+ abcdefghijklmn
+a.....2..1.....
+b..............
+c..............
+d..............
+e..............
+f..............
+g..............
+h..............
+i..............
+j..............
+k..............
+l..............
+m0....3...4...5
+n..............
+o..............
+p..............
+
+Output:
+
+   x:
+   0010101
+   0010101
+   0010160
+   0567474
+   0747262
+   lbk=x-b+0236000
+
+01 means move diagonally up and right one step; do this eight times.
+60 means move up four steps.  56 means draw left three steps.  74
+means draw down four steps.  72 means draw left four steps.  62 means
+move left four steps.
+
+0236000 means there are 15 moves, or 6-bit bytes.
+
+0236000 in binary is 010011110000000000, and shifting this value
+10 bits to the right gives 01001111, where only the 6 least significant
+bits indicate the number of moves, i.e. 001111 or 15 in decimal.
+
+The following explanation separates out each move onto its own line.
+Further it decodes each move into binary, and separates out and interprets
+the three distance, visibility and direction fields.  Finally each line
+ends with a comment indicating which input command generated the output move:
+
+move	move	move	dist	vis	direc	dist	vis	direc	input
+number  octal   binary	binary	binary	binary	decimal	text	text	command
+------  -----	------	------	------	------	-------	----	----	-------
+1       001	000001	00	0	001	1	false	up right ai
+2       001	000001  00	0	001	1	false	up right ai
+3       001	000001  00	0	001	1	false	up right ai
+4       001	000001  00	0	001	1	false	up right ai
+5       001	000001  00	0	001	1	false	up right ai
+6       001	000001  00	0	001	1	false	up right ai
+7       001	000001  00	0	001	1	false	up right ai
+8       001	000001  00	0	001	1	false	up right ai
+9       060	110000  11	0	000	4	false	up	 ai
+a       056	101110  10	1	110	3	true	left	 v af
+b       074	111100  11	1	100	4	true	down	 mf
+c       074	111100  11	1	100	4	true	down	 mf
+d       074	111100  11	1	100	4	true	down	 mf
+e       072	111010  11	1	010	4	true	right	 mj
+f       062	110010  11	0	010	4	false	right	 x mn
+
+This can be interpreted on a grid by starting at ma (row n, column a)
+denoted by a 0 and following the moves denoted by their corresponding
+move number.  Note that after the final move, f, the location being
+outside of the character box corresponds to the location ma of the
+next character to the right.  To the right is the same character where
+x:s denote drawn pixels and . denote undrawn pixels.
