general questions about assembler

[Joe Maroni]

i know there are many dissassembler for the amiga, but is a tool existing to convert ASM Code to HEX values and backward ??

the disassemblers i know just convert (disassemble) from binary code to mnenomics.

and how much different commands/hex values are able on an Amiga machine ???

I don't know, but you can always hex edit the binary file.

[jotd]

commands have addressing modes, hence a lot more hex values than operands.

for the commands, try this: http://aminet.net/search?query=68000+guide

Not quite sure what you're trying to achieve but in the program Resource you can set the datatype to longwords, words etc and just dump any type of file back to dc.l type statements, or set a start and end point, and save the file as binary etc.

For ASM to hex, you can just assemble the file and then use the above to output it as hex values.

If you are trying to convert assembler mnemonics to HEX then good luck. It is a project I tried starting a few months back and found no software that does it. There are plenty of people around that can convert the binary/HEX code to the mnemonics though.

The closest you can get to getting the HEX versions of the code is either:

a) See attached document
b) Add garbage to the end of the mnemonic in Devpac 2 & assemble it. Devpac will halt with an error, but displays the HEX code on the left (after line number and some other number).

Use the -a option of the newest ADis or IRA...

http://www.heywheel.com/matthey/Amiga/ADis.lha
http://aminet.net/dev/asm/ira.lha

For example with ADis -m -a test

MC68060


SECTION hunk_0,CODE

lab_0:
lea (lab_14c0,pc),a0 ; 0 : 41fa 6
moveq #0,d0 ; 4 : 7000
rts ; 6 : 4e75

The formatting starting at the comment is...

; relocatable offset in hex : hex value of instruction

IRA does the same except it doesn't seperate each word. Resource works a little different but can do it also by marking the code as data as Codetapper points out.

Thanks for those links. Clearly I didn't search hard enough (or use the right keywords).

Didn't quite understand the original question, but asm to binary uses an assembler like asm-one. When you have the binary file, you can convert it to .hex (f.ex. for burning EPROMs) with lots of different software.

Me, I use an EPROM burner that can burn binary files and convert every .hex file to binary. It seems kind of strange to me to have a binary file as a text file. If I want to change the binary file I use any hex editor like an assembler or monitor, or for example HexEdit (softpedia.com) if it's PC. But actually it's simpler to open the .bin file in WinUAE and use AsmOne.

This is just a general comment on hex/bin/edit stuff, if you phrase your post differently maybe I'll know what you want to achieve.

I'm not sure if it is what you need, but try John Fielden's programming pages in the online commodore enthusiasts magazine.
