No, I don't actually. Been a long time. May look around on my (now Debian testing amd64) development machine to see if I find any traces of that. Will have to set up OpenWatcom on that machine to attempt this again, should I decide to.

For my current projects I usually need at least 2.10, I did some testing recently but don't remember which exact versions worked. (And Google's Hangouts is difficult to search.) I think some specific 2.09.xx versions worked too.

The memory problem I'd noted back then is truer than ever. The current (symbolic branch) lDebug source is simply way too large. Without *extensive* work to do some kind of swapping this won't ever be able to be assembled in 86 Mode. Here's a current count (not including the symsnip and lmacros files):


ldebug/source$ for file in *.asm *.mac; do echo "$file"; done >> filelist.txt
ldebug/source$ cntlines @filelist.txt

Total lines:    41120
