Hello Mark. You information is great, I hope this case could be promoted in any way... may be in the emscripten webpage or any other place so other people could go for commercial applications with some sucess cases.
I don't know if you are just fun about COBOL, but I check it without any prior knowledge and I found this information: **************************************************** OpenCOBOL -- http://opencobol.org/ OpenCOBOL is an open-source COBOL compiler. OpenCOBOL implements a substantial part of the COBOL 85 and COBOL 2002 standards, as well as many extensions of the existent COBOL compilers. OpenCOBOL translates COBOL into C and compiles the translated code using the native C compiler. You can build your COBOL programs on various platforms, including Unix/Linux, Mac OS X, and Microsoft Windows. cobc binaries exist for HP/UX, zOS, SPARC, RS6000, AS/400 and more. **************************************************** So its possible to translate COBOL source code to C, and then use emscripten to executed it on javascript. I don't know if there is some COBOL Frontend project for llvm, but I belive its also possible.
