Can you be more specific? This is the comment block at the top of the file. I downloaded the doshexed_v1.3g_freedos_2023.zip file from your website, but it looks really old.

This editor will complain it's out of > memory if we're trying to open a file that won't entirely fit into the I had a look at the DOSHEXED source code, because it doesn't have any user documentation. It reads "Added dosmem free check, wont load if document is greater than ramavail." So, it's definitely a limitation of DOSHEXED. Do we really need DOSHEXED in a FreeDOS distro, when we already have UHEX? UHEX is open source (2-clause BSD) and works even on a 808x processor. > leftover conventional memory (<1MiB).

Try this: * https://www.sac.sk/download/utilprog/hiew650.zip This is the well-known "freeware" Hacker's View (HIEW) hex editor. IIRC, its built-in disassembler can handle up through Pentium III. There are others like BIEW/BEYE and QVIEW, both with sources, that try to mimic the same interface and features. * https://sourceforge.net/projects/beye/files/biew/6.1.0/ * https://sourceforge.net/p/beye/bugs/38/ * https://www.sac.sk/download/utilprog/biew562.arj * https://www.sac.sk/download/utilprog/qv291src.zip I still use HIEW a lot, it's pretty rock solid. I have used the others occasionally, but I can't say they're quite bug-free. Your mileage may vary. (If you want automated hex editing for batch files, I have other tools in MetaDOS. I also added recompiling BIEW as one of my tests.) Just FYI. ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user

Sure, but that's not very portable code. And it is not enough anyway. To handle 4 GB one would also need to: - replace all 'long' position tracking variables by unsigned long - handle errors in a different way (than passing -1) - use a non-portable construct to replace fseek() - and probably more that I don't think about right away Mateusz ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user

[Freedos-user] DOSHEXED - memory bug
Hi everyone, I'm trying to edit different files with DOSHEXED from FreeDOS 1.3RC5 CD and it's just disappointing. This editor will complain it's out of memory if we're trying to open a file that won't entirely fit into the leftover conventional memory (<1MiB). I tried editing LOTUS.DAT (approx 1.4MB, from Lotus 3: The Ultimate Challenge) and Stargunner's SETUP.EXE. Luckily the second one fits, given you don't load too many drivers in DOS. Is there any other hex editor for FreeDOS, which works a lot better?
