Dear comp.os.ms-windows.programmer.win32, and alt.lang.asm,

As the click-bait title says, I tried to create a /hello world/ appli-
cation with Microsoft's venerable MASM, but it's called ml64 now.-a For
some weird reason.-a Why couldn't it have just been MASM.EXE?

Anyway, none of the examples at

-ahttps://stackoverflow.com/questions/70661294/print-hello-in-64-bit-masm

and please forgive the long U.R.L., I don't use shorteners anymore; work
for me.-a It might be something about my eleven Windows, or the fact that
I'm using Visual Studio of the year of the Lord 2026, and not an earlier edition.

Is there a kind soul able to show me exactly how to compile, and build a /hello world/ with Microsoft's venerable MASM of the year of the Lord
2026?

However, I was able to get the following yasm example to work on Windows eleven. I still don't know how to use MASM, nor yasm on NetBSD.

Well, my signature is missing, but I think nobody cares. I'm adding comp.lang.asm to the discussion.

Then I got the following to work as well. I'm now ready to lean assem-
bly on Windows, with C functions! I hope there are no showstoppers on
the way.

Please excuse the long lines, and fix them yourself!


Happy assembly coding on Windows!
