Bob Perl-Sensitive Sunglasses  Comment on  You are right, of
course. Thanks for pointing it out. I absentmindedly copied the
sequence from the result of an early script where the nodes were
in that order. Using the same structure that we have in the
company example, the post-order traversal is correct. Just
change "callback" into "callbackback" and the printout will be:
net empl: 6 budget: 25000 str empl: 8 budget: 65000 sales empl:
