Quick docs for JamaicaMON SLJ 1/31/97 sjudd@ffd2.com
-------------------------

Last update: 12/14/99

version 3.0:

	v3.0 incorporates PeekPokePatch, making 24-bit load/save
	possible.   PPP also adds hex numbers to BASIC along with
	24-bit addresses for PEEK, POKE, SYS, and WAIT.  Thus you can
	do things like

		SYS $8000
		POKE $123456,255
		LOAD"BLAH",8,$020000
		SAVE"DATA",12,$040000,$093800

	from the BASIC prompt.  For more info on PPP, visit the
	page in the Fridge; note that jammon v3.0 uses a special
	version of PPP that can be relocated.


Format:
 byte  	two characters -- use 09 instead of 9.  Exception is
	load and save, where the device number may be 1 or 2 chars
	(and is in _decimal_ i.e. not hex).

 addr	16 or 24 bits -- two or three bytes.

	If a 16-bit address is used, the current value of PBR is 
	prepended to form a 24-bit address (e.g. d c000 will disassemble 
	at $01C000 if PBR=01).

Notes:
	If E=1 then X=M=1

	24-bit load/save is supported via CMD load/save patch.

	Requires a SuperCPU!

Commands
--------

a	a addr command
	Assemble.  Numbers/addresses are in hex and prefixed by a $.
	<!> are valid in absolute addressing to force 8/16/24 bit addresses.
	The flags (see r) determine whether immediate mode is be assembled
	as 8 or 16 bits.  !x and !m may be used to flip the X and M bits
	during assembly (!! will flip both; note that X=M=1 when e=1).

d	d addr
	Disassemble one screen.

<-	<-
	Disassemble one screen backwards from current address.

{lira}	{lira}
	Toggle whether disassembler follows REP and SEP.  Note that if E=1
	then X=M=1 always.  (I felt the lira key was growing lonely from
	neglect, so he gets the toggle honor).

,	, addr byte1 [byte2 ...]
 	Re-disassemble.  The bytes following the address are read in and 
	stored, and the screen is re-disassembled.

p	p addr1 addr2
	Disassemble range.

#	#number
	Number conversion.  Argument "number" may be hex ($), binary (%),
	decimal (no prefix), or character (').

r/e	no args
	Display regs/alternate regs.  Note that value of flags, PBR,
	and $01 can alter certain commands: flags determine 8/16 bit
	#immediate mode assembly and disassembly, PBR changes default
	address locations, and $01 affects any memory read (disassembly,
	memory display, etc.)

m	m [addr1 [addr2]]
	Display memory.  If a second address is specified, display memory
	range.  If no address is specified, then continuously display
	memory from the current address.

i	i [addr1 [addr2]]
 	Display memory+text.  Memory can't be modified like m command
	(not enough room on the screen line!).

i*	i* [addr1 [addr2]]
	Display memory as screen codes.

h	h addr1 addr2 byte1 [byte2 ...] or h addr1 addr2 "string"
 	Hunt.

f	f addr1 addr2 byte
  	Fill range of memory with specified byte.

t	t addr1 addr2 dest
	Transfer memory.

n	n addr1 addr2 addr3 dest
	Relocate code.  addr1=start of code, addr2=start of variables,
	and addr3=end of variables.  Transfers memory and updates addresses
	between addr1 and addr2.  This way, programs (like JamaicaMON!) that 
	have code followed by variables and tables can be relocated in one 
	swell foop (use w to get jamaicamon addresses).  Yep, you're SOL
	if you just want to relocate a table -- maybe a future update?

	To relocate jammon, use w, set the dest address, relocate the
	code, and g dest.

w	no args
 	Where am I?  Prints addresses of jammon code, vars, and end.

;^:	various
	Alter regs/alternate regs/memory (printed by r and e)

l	l "filename",dev[,addr]
	Load file (to addr if specified), where addr can be 24-bits.

s	s "filename",dev,addr1,addr2
	Save file, addr1 and 2 can be up to 24-bits.

@	@ @$ @#dev @command
	Send disk command.  @ reads the error channel.  @$ displays the
	directory.  @#dev changes the current device to dev.  @command
	sends "command" to the drive.

b	b addr
	Set breakpoint.  The address and previous contents are remembered;
	if the monitor is then re-entered from this point, the previous
	contents are restored.  Only one breakpoint may be set at a time.

g	g [addr]
	Restore registers and go.  If no address is specified, it will go to PC.

z	z [addr]
	Zingle ztep.  Zame az go, but zets a breakpoint at ze next inztruction.
	(Note that branches, JSRs, etc. will not be followed).

x	no args
	Exit to basic.

?	no args
	List available command keys
