Test MASM programs online
I'm trying to find a way to test assembly language programs online using MASM syntax, but I haven't yet found any way to do this. Are there any online tools that will make it possible to test MASM programs online (like jsfiddle or ideone, but for MASM?)
As of earlier today, you can, at tryitonline.net. Although technically that's JWasm and not Masm, JWasm is an open source assembly compiler that functions identically to Masm.
Note, however, that TIO is powered by Linux, so Windows libraries are unavailable, and system calls are done differently.
