Code:


RTN                             // could be removed, END is a super RTN
END

Correction: not "could" be removed, but "should" be removed.
END is not just a marker that indicates where a program ends. It is an executable instruction, and when it is executed, it performs EXACTLY the same operation as RTN.
There is never, ever, any reason to put a RTN right before an END. Never ever. And when you do, a kitten dies somewhere.

I was just afraid to remove some byte from a program with synthetic instructions...
