Overview |

< |
"mon" is an interactive command-driven file manipulation tool that is inspired |
| 21 |
< |
by the "Amiga Monitor" by Timo Rossi <trossi@jyu.fi>. It has commands and |
| 22 |
< |
features similar to a machine code monitor/debugger, but it is not intended |
| 23 |
< |
to be used for debugging. It doesn't operate on physical or virtual RAM |
| 24 |
< |
locations of a process but rather on a fixed-size (but adjustable) buffer with |
| 25 |
< |
adresses starting at 0. Also, there are no commands to trace code, set |
| 25 |
< |
breakpoints etc. There are, however, built-in PowerPC, 680x0, 6502 and 8080 |
| 26 |
< |
disassemblers. |

Installation |

|
----- |
| 36 |
|
|
| 37 |
|
mon can be started from the Shell or from the Tracker (BeOS), but command line |
| 38 |
< |
history doesn't work when started from the Tracker). If you give no command |
| 39 |
< |
line arguments, mon enters interactive mode. Otherwise, all arguments are |
| 40 |
< |
interpreted and executed as mon commands. The default buffer size is 1MB. |

Options: |
| 41 |
> |
-m enables symbolic MacOS A-Trap and low memory globals display in the |
| 42 |

680x0 disassembler |
| 43 |

-r makes mon operate in real (virtual) memory space instead of an allocated |
| 44 |

buffer |

If no additional command line arguments are given, mon enters interactive |
| 47 |

mode. Otherwise, all remaining arguments are interpreted and executed as mon |
| 48 |

commands. |

When mon is started as "rmon", it enters "real mode". That is, all memory |
| 337 |
– |
related functions no longer operate on the buffer but on "real" (virtual) |
| 338 |
– |
memory. Unless you are writing Mac emulators, this is probably of not much |
| 339 |
– |
use. :-) |
