1575.0. "DEASSEMBLER" by VALUES::LINCE () Wed Aug 03 1988 17:15

    Hi - I'm looking for a deassembler/debugger that will deassemble
    programs. specifically, I'd like to find out some of the 'secrets'
    that some of these copy protected programs use. I've seen something
    like this for the IBM that touts that it will even display the
    developers comments.
    
    	Anything for the Amy ?

That's weird, the compiler/assembler ignores comments.  If it didn't we
could/should get some pretty huge executables! :-)

1575.2Perhaps you misread itMILRAT::WALLACEWed Aug 03 1988 21:465
    I've seen ads for disassemblers that allow you to associate symbols
    with code locations and ADD comments to the disassemlbed listing.
    But I concur with .1 you can't get comments where there are none.

1575.3Found on the netNAC::PLOUFFBeautiful downtown LittletonThu Aug 11 1988 20:5422
    Two public domain disassemblers are on-line at:
    
    MVCAD3::USER0:[AMIGA.USENET]DIS*.SH
    MVCAD3::USER0:[AMIGA.FF128]DIS.ARC
    
    The first (two files) is in Unix shell format and needs both 'shar'
    and 'uudecode' to unpack.  I have tried this one and it works, though
    is no great shakes.
    
    Several ads for disassemblers have appeared lately in the backs
    of magazines.  Simple ones (like the PD stuff) just disassemble
    over the range of addresses given, and maybe allow you to build
    symbol tables manually.  I would expect commercial products worth
    buying to do things like know symbols for library functions, do
    branch testing to identify all code segments, and be fairly smart
    about deciding if a section is code or data.
    
    Re: show the developers' comments.  I remember a product for CP/M
    which was a disassembler, but would give you a copy of the operating
    system source code with many labels and comments!  This was a thin
    subterfuge to allow the publisher to sell source code without getting
    into trouble with Digital Research, the CP/M vendor.
