Conference vaxuum::online_bookbuilding

    I believe that the correct way to do what you want is:
    
    <HEAD1>(Head title<FOOTREF>(1)\hd_sym)
    <FOOTNOTE_TEXT>(1\Text for the footnote)
    <P>
    Blah blah blah....<FOOTREF>(1)
    

Could an <online_chunk> tag between a reference to a symbol and the place where
the symbol is defined cause one of these "undefined symbol" errors?  I got the
following message:

BOOKWRITER ERROR--The following symbols are undefined:
        pgid = 388, offset =  28221, symbol = 'EX_FB_ESC'
%DVC-E-OUTPUTFAIL, error writing to output file
-DVC-I-INPUTFILE, input file is:    SYS$LOGIN_DEVICE:[EPPES.GRAPHICS]PROFILE.
-DVC-I-ONPAGE, on page [37] 
%DVC-E-BOOKABORT, aborting run -- book  SYS$LOGIN_DEVICE:[EPPES.GRAPHICS]PROFIL
  EPPES        job terminated at  7-SEP-1990 13:28:39.65


When I searched my source files for EX_FB_ESC, I came up with the following
coding:


<reference>(ex_fb_esc) illustrates how this escape is used.

<ONLINE_CHUNK>

<EXAMPLE>(Using the FORTRAN Escape Function --440\ex_fb_esc)
<CODE_EXAMPLE>
   etc.


I commented the <online_chunk> tag out (not sure why it was there, anyway;
these are not my own files) and I'm currently building the book again to see
whether it made a difference.  However, the book takes about 3 hours (elapsed
time) to build...

This is DOCUMENT V1.2-B, by the way, and VMS 5.3.

RE .2 - Well, commenting out that <online_chunk> tag didn't help.  I still got
the same message.  The symbol *is* defined and is only referenced just before
the example, as shown in my previous reply.  There are no other references to
it (at least, a search of all the .SDML files didn't turn up any others).

Any suggestions?  Oh, I'm using the CUP.TEST_ONLINE doctype, by the way, if that
makes any difference.  (And the book built fine for PS output.)

    Nina, could you send me a pointer to the .SDML file?  I'll run some
    tests on it here and let you know what I find.

    The problem turned out to be the use of an <ONLINE_CHUNK> tag in a
    formal example.  Removing it fixed the problem.
    
    As the documentation states, the <ONLINE_CHUNK> tag is NOT to be used
    in formal examples and tables.

Since I teach a class on coding SDML files for Bookreader, I'd just like to 
state, for the record, that I didn't code this file!  (I also mentioned this in
a previous reply.)  Must keep my reputation intact, you know...  :-)  :-)

I'd also like to express my enormous appreciation and gratitude to Wayne for
tracking down the problem.  Thanks, Wayne!  Now, if you can just do something
about a message that reports "undefined symbol" when it really means "you have
an <online_chunk> where you shouldn't, you dodo!"  :-)

    Ask and ye..... whatever....  ;^)
    
    In the next version of the software, the tag translator will check to
    see if <ONLINE_CHUNK> tags are coded in formal topics and issue an
    error message if so.
    
    Thanks,
