Well, sort of. The BASIC can stand alone, but the Perl is something of a fragile/one-off/single purpose BASIC interpreter. So, the BASIC works without the Perl, but the Perl doesn't work without the BASIC.

I like the q$ idea...perhaps I can get more than 1/2 a polyglot next time.

Thanks for the feedback...

Update: I added something a bit closer to a polygot on the original node. Thanks BooK !
