#X text 19 42 Every modern programming language will have various "looping"
mechanisms: either in the form of an object \, or as a data structure.
For example in Visual Basic:;
#X text 30 100 DO UNTIL i = 100;
#X text 30 114 i = i + 1;
#X text 31 85 i = 0;
#X text 30 129 LOOP;
#X text 15 210 And now PD's version of the above programming structures:
;
#X obj 24 257 until;
#X msg 24 237 100;
#X obj 24 277 print i;
#X text 17 304 If you start [until] with a "bang" \, it will begin
an infinite loop! Please plan ahead in this case so that there is a
mechanism in place to stop the loop - otherwise PD will effectively
freeze.;
#X text 17 361 HOW TO FREEZE PD;
#X msg 25 384 bang;
#X obj 25 404 until;
#X obj 25 424 print;
#X text 63 384 DO NOT CLICK. DO NOT CLICK. DO NOT CLICK.;
#X text 66 404 If you click \, click the "close window" (X) button
on PD's terminal window - or reboot the computer.;
#X text 17 145 OR:;
#X text 29 161 FOR i = 0 TO 100;
#X text 28 187 NEXT;
#X text 29 175 ' do something;
#X text 26 493 The example below includes a method to stop the loop
to prevent PD from looping infinitely.;
#X text 434 44 If you start [until] with a number \, it iterates that
number of times. The [uzi] object in MAX works the same way.;
#X obj 441 131 until;
#X msg 441 84 100;
#X obj 441 151 print i;
#X msg 469 91 3;
#X msg 497 98 42;
#X text 26 451 The [until] object's left inlet starts a loop in which
it outputs "bang" until its right inlet gets a "bang" which stops it.

#X text 67 13 - LOOPing mechanism;
#X text 442 580 This document was updated for PD version 0.35 test
26 by Dave Sabine as part of a project called pddp proposed by Krzysztof
Czaja to build comprehensive documentation for PD.;
#X text 436 185 RELATED OBJECTS;
#X text 441 204 ?? This author does not know of any other native looping
mechanisms in PD.;

#X text 27 63 These objects are offered in PD only if you have downloaded
and properly installed the appropriate library. These objects may or
may not exist in a single library.;
#X text 26 112 The best places to find information about PD's libraries
is:;
#X text 23 134 www.pure-data.org and click on "Downloads" then "Software"
