379.0. "ACCVIO when <ONLINE_TITLE> used with formal figure" by BOOKIE::EPPES (I&#039;m not making this up, you know) Fri Oct 12 1990 17:15

During the CUP OLD Tools Training: Text class in Chelmsford today, we ran
into an interesting feature :-) of the <ONLINE_TITLE> tag: it apparently
causes an ACCVIO when used with a formal topic (figures, in this case).
In the class, the students code some SDML files for Bookreader output,
build a book, and view it with Bookreader.  Some people decided to try
using <ONLINE_TITLE> before some formal figures that had long captions,
and since I didn't know offhand of any restriction against it, I said go
right ahead.

Well, the upshot was that during device conversion, an ACCVIO would occur
when the figure files were being included.  We eventually discerned that
it pertained to the presence of <ONLINE_TITLE> tags with two figures.  When we
removed those <ONLINE_TITLE> tags, the book built successfully. 

Oddly enough, in another bookbuild in the class, there was an <ONLINE_TITLE>
tag with *one* figure, and that book built successfully.  However, the title
specified with the tag was not displayed; the regular caption was.  *But*
there was weirdness at the end of the caption in the form of:  {char37}

I talked to Mary on the phone about this, and she said the {char37} is a
TeX sequence.  She also said to post a note here, so here it is.  :-)

I was able to reproduce this behavior on BOOKIE, my home system.
Below is the log file.  All the files - .SDML, figures, .DVI, etc. - are
in the directory BOOKIE::USER2:[EPPES.DOC_TEST].  CH3.SDML is the file with
the <ONLINE_TITLE> tag before the formal figure.

Have fun!  :-)

    It was a bug in V1.2B that's been fixed for V2.0. 
    For 1.2B, if you keep the number of characters in the title under 50 
    it'll work.

In which title?  The title of the figure (/table/example)?  Surely not the title
specified with <ONLINE_TITLE>....?

    >>  Surely not the title specified with <ONLINE_TITLE>....?
        
      Unfortunately yes
    
    
    MIke                              

    Regardless of the length of the title, the <online_title> tag did
    not work properly with formal elements. (Actually, it did not work
    at all.) But, as Nina points out, it's perfectly reasonable to
    expect it to work in that context so I have made the necessary
    modifications to the tag, and in DOCUMENT V2.0 you will be able to
    use <online_title> to display shorter versions of the titles of
    formal figures, tables, and examples.
    
    Thanks,
    
    Mary

RE .2 and .3 - The reason I said "Surely not not the title specified with 
<ONLINE_TITLE>....?" was because obviously you'd keep that title well under 50
characters long; otherwise there's no point in using that tag, is there?  :-)

Thanks, Mary and Mike, for your reponses (and fixes!).

I've used <online_popup> in a similar way for informal elements.
That is, I enter a brief caption instead of simply saying
"Figure." This helps when you've opened several informal figures
in Bookreader and reduced them to icons (for example, in hardware
installation sections). The figures don't need captions in
hardcopy, but the informal captions are useful in Bookreader.

The only problem with this approach is that the punctuation
in the hotspot text is awkward. Is there any solution to this?
Also, is there a limit to the number of characters you can enter
for an <online_popup> argument?

    RE .6: I've never been entirely happy with the <online_popup> output
    myself (and I invented it!) but have failed to come up with any good
    alternative (or at least one I like better). (And let's face it, as
    long as there were only the occasional moans and groans about it, it
    didn't seem like a high priority...)
    
    One alternative I did think of (but it good a very lukewarm reception
    hereabouts) is to simply let whatever the user enters be the hotspot.
    Text, punctuation, whatever you type, just as you type it, would be hot.
    
    Suggestions are welcome (but will not make it into DOCUMENT V2).
    
    There is no limit to the number of characters you can enter for an
    <online_popup> argument, although there is a limit of 254 characters
    (right, Mike?) for a title in the title bar. For Bookreader V1, there
    was a de facto limit because hotspots could not break across lines.
    For that case, a one-word argument was the ideal. But Bookreader V2
    implemented hotspots differently, and they can now break across as
    many lines as necessary.
