J comes with a Qt IDE, which has a function "dissect" that displays a graphical parse tree of an expression.

load 'debug/dissect'

dissect '(+/ % #) ? 10 $ 100'

Thanks! I haven't touched J in about ten years -- and I never used dissect -- and I never did anything serious in it, just about thirty project euler problems for fun.

That should have an ASCII art alternative too.
