+Pd release 0.23 and onward include objects for managing lists of data.  The
+objects allow you to describe data structures and how they are viewed
+("template objects") and to traverse lists ("traversal objects.")
+
+The rest of this file gives a highly condensed summary of what's there; the 
+patches, starting with "1.scalars.pd", act as a tutorial.
+
+1. TEMPLATE OBJECTS.
+
+templates describe data structures.  You can add an item to a data structure
+using "field" or ask for a shape to be drawn using a "display command."
+
+1.1. "template" -- data structure.
+
+usage, "template <field1> <field2> ..."
+
+where the fields are either "float <name>", "symbol <name>", "list <name>"
+(don't try that yet); or "array <name> <template-for-elements>.
+
+1.2.  DISPLAY COMMANDS.
+
+
+These are objects which ask Pd to draw a shape corresponding to some fields
+of the datum.
+
+1.2.1.  POLYGONS and CURVES.
+
+polygons:   	 polygon <outline-color> <line-width> <x, y> ...
+filled polygons: fpolygon <fill-color> <outline-color> <line-width> <x, y> ...
+curves:   	 curve <outline-color> <line-width> <x, y> ...
+filled curves:   fcurve <fill-color> <outline-color> <line-width> <x, y> ...
+
+Each argument can either be a number or a symbol.  If a symbol, it's the
+name of a field (which must be a "float) which specifies the vaiue.
+So for instance in the "1.scalar.pd" example, in the template "template1",
+the object "fpolygon 244 q 5 0 0 20 z 40 0" draws a filled polygon whose
+interior color is 244 (red 2, green 4, blue 4) but whose outline color
+depends on the value of the field "q".  Its coordinates describe a triangle
+whose altitude is given by "z."
+
+1.2.2  PLOT.
+
+The "plot" objects plots an array field as shown in 5_array.pd.
+
+2.  TRAVERSAL.
+
+In this release of Pd, you can only traverse lists all of whose elements 
+belong to the same template; this restriction will be relaxed in a future
+release.  You "traverse" a list either to build it, to get its elements,
+or to change their values.
+
+2.1.  POINTER.
+
+The "pointer" object can be used to refer to an element of a list.  Its
+methods are:
+
+2.1.1.  traverse <symbol>.
+
+Point to the "head" of a list.  The symbol should match the name of a Pd
+window holding the list.  The pointer is output, but you can't set or get the
+fields of the "head" pointer; you can only get the "next" element or "append"
+to the list.
+
+2.1.2.  next.  Goes to the next element of the list.  Either the pointer
+is output on the left side, or else a "bang" at right tells you that no
+more objects are forthcoming.
+
+2.1.3.  bang.
+outputs the current pointer.
+
+2.2.  APPEND.  Adds an element of the specified template to the list.  You
+specify what fields you want to supply and the last inlet takes a pointer to
+the element you want to "append" after.
+
+2.3.  GET.
+
+    get <template> <field...>
+    
+send it a pointer to an object belonging to the <template> and it outputs
+the (floating-point) fields.
+
+2.4.  SET.
+
+    set <template> <field...>
+    
+send it a pointer (at the rightmost inlet) and values for the specified
+fields, and their values are changed accordingly.
+
+2.5.  GETSIZE.
+
+    getsize <template> <array-field>
+    
+outputs the size of the named field, which must be an array, when it receives
+a pointer to the owner as input.
+
+2.6.  SETSIZE.
+
+    setsize <template> <array-field>
+    
+Send it a pointer to the owner (right inlet) and then the desired size
+(left inlet) and the array is resized.  If a template contains an array,
+each scalar belonging to the template can have its own size for the array.
+
+2.7. ELEMENT.
+
+    element <template> <array-field>
+
+Pass it an index and a pointer and it outputs a pointer to an element of the
+array.

+done using two objects \, "pointer" which does the traversal \, and
+"get" which \, given a pointer to a scalar \, extracts numeric quantities
+from it.;
+#X text 14 85 You can send the "pointer" object a "traverse" message
+to point it to the head of the list. The argument "pd-data2" indicates
+the Pd window named "data2." The head of the list means \, not the
+first scalar in the list \, but the position before the first scalar
+\, which is a valid pointer in Pd but has no data or template.;
+#X text 14 180 The "next" message tells the "pointer" object to go
+to the next scalar in the list and output it. If there are no more
+\, "pointer" outputs a bang at right.;
+#X text 19 424 The "get" object takes a pointer \, checks that its
+template agrees with what "get" is expecting \, i.e. \, "template2"
+\, and if so outputs the values of x \, y \, z \, and q in the usual
+reverse order.;
+#X text 18 492 The pointer sent from "pointer" to "get" is an elementary
+Pd type on a level with "float" and "symbol".;

+(x \, y) location \, width \, height \, and color. A new feature is
+that the color is also getting printed out under the rectangles. This
+is done using the "drawnumber" object in the template.;

+#X text 45 99 Getting parameter values is as in the previous patch
+\; however \, as you traverse the list with "next" messages the new

+the template name and the name of the field they will set. You can
+drag on the five number boxes (after selecting an object with "traverse"
+and "next" messages) to change its location \, shape \, and color.

+#X text 13 4 This patch shows an example of how to use data collections
+as musical sequences (with apologies to Yuasa and Stockhausen). Here
+the black traces show dynamics and the colored ones show pitch. The
+fatness of the pitch traces give bandwidth. Any of the three can change
+over the life of the event.;
+#X text 11 97 To hear the result \, turn the volume up to 70 or so
+(higher if it's not loud enough the first time) and hit "start". You
+can set the tempo lower if that helps you follow the "score" the first
+couple of times.;

+#X text 10 259 This confuses Tk's scroll bars \, by the way \, and
+when you resize the window the image still sticks to the top and not
+the bottom of the window as it should. When you resize a canvas with
+y having positive units (growing upward) \, just hit 'save' and Pd
+will check the scrolling and correct if necessary.;
+#X text 10 161 Note the screen units in the "data" window (open it
+and get "properties" to see them.) Normally \, there are -1 y units
+per pixel - that is \, adding 1 to y moves down one pixel. This is
+the "natural" y unit for most drawing programs. In the data window
+\, each pixel is 0.25 units \, meaning that adding one to a 'y' value
+moves it up four pixels.;

+frequency shifting and/or FM spectra. Print and cut in half down the
+middle. If you know the pitches associated with two frequencies a and
+b \, align the pitch of a on the left side against the zero-frequency
+marker on the right side. Then find the pitch of b on the right \,
+and the matching pitch on the left corresponds to the frequency a+b.
+To get a-b \, find b on the left and look up the corresponding pitch
+on the right.;
