p.s. your problem stems from the way that rebol evaluates 'get_data before the loop and knows nothing about a global 'line. Just for grins, you could also put get_data as a 'does inside the loop where 'line would now be in the same scope as 'get_data. as in: b: [1 2 3 4 5] foreach line b[g: does[print line] g] but is probably not a good idea.... :-) tj -- To unsubscribe from the list, just send an email to lists at rebol.com with unsubscribe as the subject.
