JWasm Alternatives

    JWasm is described as 'Masm v6 compatible assembler. It's released under the Sybase Open Watcom Public License 1.0. JWasm can be used for virtually any purpose, unlike Microsoft's free download of current Masm versions, which are for non-commercial use only'. There are five alternatives to JWasm for Windows, Linux, Haiku and Mac. The best alternative is Pelles C. It's not free, so if you're looking for a free alternative, you could try NASM or Easy code. Other great apps like JWasm are MASM Builder (Free) and Yasm (Free, Open Source).
