Mainframe COBOL to POSIX native machine language or Java is largely a solved problem. 40 year old code that hasn't been touched in 30 years "ain't broke" and likely doesn't need fixing IMHO. Our take is get it to POSIX/Java so you can sort out all the OTHER STUFF and then rewrite/re-architect at your leisure. {disclosure: we're the GCC COBOL team}.

This is a problem a compiler cannot fix, and is a very real problem.
