#X text 12 205 HELP_PATCH_AUTHORS This help patch 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. Jonathan Wilkes revised the patch to conform to the PDDP template
for Pd version 0.42.;

#X text 20 38 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 31 105 DO UNTIL i = 100;
#X text 31 119 i = i + 1;
#X text 32 90 i = 0;
#X text 31 134 LOOP;
#X text 20 245 And now Pd's version of the above programming structures:
;
#X obj 29 322 until;
#X obj 29 382 print i;
#X text 20 160 OR:;
#X text 30 186 FOR i = 0 TO 100;

#X text 116 216 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. (See the "Loops" subpatch below.);
