Just to clarify what I said before: "the secret was to use wlink instead of wcl386". I tried wlink before checking WLINK.LNK directives but obviously failed, than went back to wcl386. But in the end was on the right track when I suspected the environment setup could be the problem. Almost there.

I still can't, however, compile and link the source code typing the lines from of our old batch files. Not sure why. I'm just an "average joe", though, not a professional C coder.

Again, thanks a lot for your time and your attention.
