#X text 40 2 Dollarsign Variables in Message Boxes;
#X text 20 38 You can use "dollarsign variables" to make variable messages.
Just use a dollarsign followed by a number-- "\$1" \, "\$2" \, etc.
The numbers (starting from one) specify which element of the incoming
message should replace the variable in the outgoing message.;
#X msg 23 131 pitch \$3;
#X text 115 106 a list with three numbers;
#X msg 23 106 list 24 48 72;
#X text 83 131 replace "\$3" with the third element;
#X text 84 145 of the incoming message ("72");
#X msg 23 236 24 48 72;
#X text 83 236 implicit list with three numbers;
#X msg 23 259 pitch \$3;
#X obj 23 281 print;
#X text 83 259 third element is still "72";
#X text 20 303 It's important to note that you can't access the selector
of the message using the dollarsign variables. (In the patch above
\, "list" is the selector \, "24" is the first element \, and so on.)
Keep this in mind when using custom selectors \, as in the following:
;
#X msg 23 373 melody 67 67 67 63;
#X text 153 374 In this message \, "melody" is the selector \,;
#X text 153 389 and there are four elements (not five).;
#X msg 23 407 pitch \$4;
#X obj 23 490 print;
#X text 85 407 replace "\$4" with the fourth element ("63");
#X msg 41 459 pitch \$5;
#X msg 41 433 melody 65 65 65 62;
#X text 163 438 this will output an error--;
#X text 163 452 there is no 5th element!;
#X text 20 180 Remember that the selectors "list" and "float" can be
omitted when the first atom in a message is a float. For example \,
the following still works exactly as the patch above:;
#X text 21 514 Multiple dollarsign variables may be used together:

#X text 141 165 3) The float "3";
#X text 20 37 Even though they are not be separated by whitespace \,
semicolons and commas are actually atoms in Pd-- just like float- and
symbol-atoms. You can see this clearly in the example below:;

#X msg 22 281 Because I do not hope to turn again \, Because I do not
hope;
#X obj 22 303 print from_Ash_Wednesday;
#X text 20 210 In message boxes \, commas and semicolons are used to
separate one message from another. For example \, there are two messages
in the message box below. Each is sent separately to the [print] object
(in the order they were written):;
#X msg 23 376 1 \, 2 \, 3;
#X obj 23 398 + 10;
#X obj 23 422 print sum;
#X text 20 329 Notice that the comma itself is not included as part
of the message-- it simply tells Pd where one message ends \, and the
next begins.;

#X text 85 451 is the same as;
#X text 22 396 For messages to a single named-object \, however \,
it is probably clearer to use a message box and a [send] object \,
but you can judge for yourself:;
#X text 20 37 Like commas \, semicolons may be used to send multiple
messages from a single message box. When using a semicolon \, however
\, the message following the semicolon is re-routed to a named object
\, such as [receive] \, an array \, or a canvas. The named object is
specified by the selector of the message ("msg2r" in this example):
;
#X text 22 246 To send messages to named objects without first sending
a message to the outlet \, put an initial semicolon in the message
box:;
#X connect 3 0 4 0;
#X connect 6 0 5 0;

#X text 168 256 - other messages will cause the message box to send
its message as output \, except for the "special messages" that are
used to change the content of a message box. Click the subpatch below
to view these "special messages":;
#X text 168 480 - a comma may be used to separate multiple messages:
;
#X text 178 515 - a semicolon may be used to send messages nonlocally:
;
#X text 168 406 - message boxes can contain any number of float and/or
symbol arguments. Message boxes may also contain special "dollar-sign
variables" \, used to grab data from an incoming message. Click the
subpatch below for more info:;
