JWasm ended in 2014. New versions are available as projects ASMC or UASM on GitHub.

Great tool. I was finding a compiler for old dos and this works very well. It's good to know this works with x64 as well.

Very good alternative to masm and tasm in most cases.

Great job!

A very good alternative to Masm, and a lot faster. Almost fully compatible, the remaining 0.1% are in the bugs list; before embarking on a bigger project, study that list, although usually these bugs have no relevance for the average user ;-)
