Is there any reason he would have heard of those? They're all pretty fringe, arguably moreso than Forth, for some of them.
Some of these do look neat: I've had an interest in both Ada and Oberon, although I haven't been able to get over the verbosity and unpleasant syntax of either (it's not COBOL, or anything, but it's not nice).
OTOH, I am immediately suspicious of any product that claims it's professional and also has BASIC in the name...
Ada is not fringe. It's used by many large companies, although less and less these for new projects these days. There are some huge Ada codebases being maintained in industry, particularly in the aviation industry.
