Hi TeXmacs folks,

I'm trying to get more sophisticated and say-what-I-mean in my use of 
TeXmacs, but am having trouble figuring out how to introduce an 
automatic counter that resets at each chapter.  I'm trying to follow the 
descriptions in 
http://www.texmacs.org/tmdoc/main/styles/std/std-counter-dtd.en.html, 
but somehow I think I'm missing something.  I have attached an example 
TeXmacs file that illustrates my woes.  My apologies if this is obvious 
from the documentation, but somehow I'm not getting it; I'm not sure 
whether my basic use of counters is misguided but looks like it's 
working (and thus is confusing me), or whether instead I am using basic 
counters correctly but have blown it when it comes to counter groups.

Thanks for any help you can provide,
    Dave W

  <chapter|In Which an Attempt is Made to Create Some Counters>

  This is a test of creating some counters, as I try to figure out how to get
  a counter that auto-resets at each chapter. \ For example, suppose I want
  to introduce a 'thingy', each of which is numbered, and in which the
  numbers reset for each chapter.

  \;

  This inquiry is based on what I see in the online instructions at
  
<verbatim|http://www.texmacs.org/tmdoc/main/styles/std/std-counter-dtd.en.html>

  \;

  I think I can get a plain counter, plain-thingy, but not one that resets
  (which I'm calling good-thingy). \ Here are the definitions (written first
  without backslashes, so I can find them easily in this test):

  \;

  new-counter plain-thingy: <new-counter|plain-thingy>

  check that chapter-nr gives us the chapter number: <value|chapter-nr>

  add-to-counter-group good-thingy chapter
  <add-to-counter-group|good-thingy|chapter>

  \;

  Use plain thingy via plain-thingy-nr: <value|plain-thingy-nr> \ <em|[NOTE
  that the web site suggests nr-plain-thingy here, but that doesn't work.]>

  inc-plain-thingy: <inc-plain-thingy>

  Use plain thingy via plain-thingy-nr: <value|plain-thingy-nr>

  inc-plain-thingy: <inc-plain-thingy>

  inc-plain-thingy: <inc-plain-thingy>

  Use plain thingy via plain-thingy-nr: <value|plain-thingy-nr>

  next-plain-thingy: <next-plain-thingy>

  Use plain thingy via plain-thingy-nr: <value|plain-thingy-nr>

  next-plain-thingy: <next-plain-thingy>

  next-plain-thingy: <next-plain-thingy>

  Use plain thingy via plain-thingy-nr: <value|plain-thingy-nr>

  \;

  At this point, I am not sure about the difference between ``inc'' and
  ``next'' for counters. They both seem to do the same thing. \ Let's try
  this all again with the good-thingy:

  \;

  Use good-thingy via good-thingy-nr: <value|good-thingy-nr>

  inc-good-thingy: <inc-good-thingy>

  Use good-thingy via good-thingy-nr: <value|good-thingy-nr> \ <em|[Hmm ...
  this doesn't show any change ]>

  next-good-thingy: <next-good-thingy>

  Use good-thingy via good-thingy-nr: <value|good-thingy-nr> \ <em|[this
  doesn't show any change either ]>

  \;

  So these don't seem to work; in my version of TeXmacs (1.0.7.3 on Ubuntu
  10.04), the second set all just shows 0.

  <chapter|In Which We See What Happens to Our Counters in a New Chapter>

  This is just a cut-and-paste of the stuff from before:

  \;

  \;

  Use plain thingy via plain-thingy-nr: <value|plain-thingy-nr>

  inc-plain-thingy: <inc-plain-thingy>

  Use plain thingy via plain-thingy-nr: <value|plain-thingy-nr>

  inc-plain-thingy: <inc-plain-thingy>

  inc-plain-thingy: <inc-plain-thingy>

  Use plain thingy via plain-thingy-nr: <value|plain-thingy-nr>

  next-plain-thingy: <next-plain-thingy>

  Use plain thingy via plain-thingy-nr: <value|plain-thingy-nr>

  next-plain-thingy: <next-plain-thingy>

  next-plain-thingy: <next-plain-thingy>

  Use plain thingy via plain-thingy-nr: <value|plain-thingy-nr>

  \;

  So my plain-thingy counter is not resetting...

  \;

  Use good-thingy via good-thingy-nr: <value|good-thingy-nr>

  inc-good-thingy: <inc-good-thingy>

  Use good-thingy via good-thingy-nr: <value|good-thingy-nr>

  next-good-thingy: <next-good-thingy>

  Use good-thingy via good-thingy-nr: <value|good-thingy-nr>

  \;

  And my good-thingy counter isn't working at all.

  \;

  Clearly I'm missing something ... but what?
