New also good? The 16-bit codegenerator of Free Pascal is only a few years old. Recent versions do away with most of the watcom tools in favor of own code.

Thanks for advise!

I had find manual for Small Assembler. This manual describe obj/omf and is more short description for OMF (may be some pages - outdated).

PS: Also, I find some fun fact. Object library (.lib) at footer-record contain dictionary. Borland's tlink works fine with empty-size dictionary, VAL-linker - require dictionary and will freeze without.

You may also want to look at http://download.xskernel.org/docs/file%20formats/omf/borland.txt for some Borland specific stuff, e.g., Dependency file definition.

And you can use the following tools to verify your .OBJ files:
1) DISPOBJ (w/o sources)
2) READOBJ (w/o sources)
3) ODU (OMF Object File Dumper) (w/ MASM sources)
4) DumpOmf (w/ JWasm/MASM sources)

Also: Digital Mars D has DUMPOBJ and Borland has TDUMP. The one from MS is called DUMPBIN.
