#X text 114 16 In Pd \, most objects carry out their functions when
they get messages in their rightmost inlets \, and their other inlets
are for storing values that can modify the next action. Here \, the
"+" object does its thing only when the left-hand input changes.;

#X text 19 433 Trigger takes any number of "bang" and "float" arguments
(among others) and copies its input to its outlets \, in the requested
forms \, in right-to-left order. Hook it to two inputs without crossing
the wires and you get the expected result. Cross the wires and you
get a memory effect.;
#X text 9 136 In Pd you must sometimes think about what order an object
is going to get its messages in. If an outlet is connected to more
than one inlet it's undefined which inlet will get the cookie first.
I've rigged this example so that the left-hand side box gets its inputs
in the good \, right-to-left order \, so that the hot inlet gets hit
when all the data are good. The "bad adder" happens to receive its
inputs in the wrong order and is perpetually doing its addition before
all the data are in. There's an object that exists solely to allow
you to control message order explicitly:;
