- Quick docs for JamaicaMON SLJ 1/31/97 sjudd@ffd2.com
- -------------------------
-
- Last update: 10/3/99
-
- version 2.2:
-
- - Note that v2 is larger than 4k; don't relocate to $C000!
-
- 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 (%),
- or decimal (no prefix).
-
- 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 $01 affects any memory read (disassembly,
- memory display, etc.)
-
- m m [addr1 [addr2]]
- Display memory. If a second address is specified, display memory
- range. If no address is specified, then continuously display
- memory from the current address.
-
- i i [addr1 [addr2]]
- Display memory+text. Memory can't be modified like m command
- (not enough room on the screen line!).
-
- i* i* [addr1 [addr2]]
- Display memory as screen codes.
-
- h h addr1 addr2 byte1 [byte2 ...] or h addr1 addr2 "string"
- Hunt.
-
- f f addr1 addr2 byte
- Fill range of memory with specified byte.
-
- t t addr1 addr2 dest
- Transfer memory.
-
- n n addr1 addr2 addr3 dest
- Relocate code. addr1=start of code, addr2=start of variables,
- and addr3=end of variables. Transfers memory and updates addresses
- between addr1 and addr2. This way, programs (like JamaicaMON!) that
- have code followed by variables and tables can be relocated in one
- swell foop (use w to get jamaicamon addresses). Yep, you're SOL
- if you just want to relocate a table -- maybe a future update?
-
- To relocate jammon, use w, set the dest address, relocate the
- code, and g dest.
-
- w no args
- Where am I? Prints addresses of jammon code, vars, and end.
-
- ;^: various
- Alter regs/alternate regs/memory (printed by r and e)
-
- l l "filename",dev[,addr]
- Load file (to addr if specified).
-
- s s "filename",dev,addr1,addr2
- Save file
-
- @ @ @$ @#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
-
- This program is in the public domain.
