Polyglot Japh

on Oct 11, 2002 at 09:13 UTC ( [id://204451]=obfuscated: print w/replies, xml ) Need Help??

My first JAPH:
The following is legal, and produces output, in BASIC, Befunge, JavaScript (place between <SCRIPT> </SCRIPT> tags in an HTML file) and Perl. 
'11';//;#  76+v,g4-\+0*55:<p0*73+5-*72p0*64*69p1*5 <
'';//;#  japh >:1- JAPH \#^_$$"egnufeB">:#,_7>88*:6^
'0'?eval("function print(japh){document.write(japh"+
''+".replace(/Perl/,'JavaScript'))}",'   '):$_=qq+0;
eval("print('Just Another Perl Hacker.')"),";\x22+;"
''/*";$\=$/;             eval               ;__END__
SUB eval (ja$,ph$)
   PRINT MID$(ja$, 8, 13); "BASIC"; MID$(ja$, 25, 8)
END SUB  '                                Dedalus */

    This really is quite nice. It worked without problems as Befunge, JavaScript, and Perl. Unfortunately, I can't get it to work as BASIC. It gives me an error with bas-1.0 and core dumps with bwbasic. Can anyone point me at a freely available BASIC interpreter for unix that won't barf on this?

    Great job!

      Um... oops. I tested the basic part in QB I'm afraid. As far as I can tell it should be legal basic code. It could be that the comment on the last line gives some trouble. You might try changing the last line to read: 
      END SUB
'*/
