Sorry about the missing pages in the User Manual.

After examining the PDF doc I created again, I realized what went wrong. When I converted the User Manual using Acrobat's auto HTML-to_PDF conversions, I told Acrobat to limit the conversion to only two hyperlink-levels deep. I didn't want Acrobat to follow hyperlinks that were outside of the User Manual. It turns out that the User manual has hyperlinks up to four four levels deep. This is why the extra pages were missing from the manual.

A more effective approach is to tell Acrobat to limit the conversions to only pages on the single User Manual path: file:///d:/program files/j software/j601c-release/system/extras/help/user/ but allow the conversion to go in as many levels deep as it needs, which should include all of the User Manual pages. This works much better, as it converts all of the HTML pages in the User Manual path. Howeve, this it makes for a much larger bookmark list, which doesn't necessarily get put in in the most appropriate sequential tree structure. Also, this conversion will not include hyperlinks to other docs outside the User Manual path. The Hyperlinks will be there, but unless you have the same path structure as I do, those links won't work.

I re-converted the user manual with the deeper link limit, and re-published it on my site http://elliscave.com/APL_J/reference/ (There is an underscore between APL & J). The new version is labeled with an 'a' in the name. Keep in mind that only links to User Manual pages will be included in the PDF doc. Links to docs outside of the user manual (such as the navigation links at the top of each page) will not operate.

All of this points up a basic issue with making a print version of a hyperlinked document. The various sub-chapters in a HTML document are not necessarily in sequential order with their parent topics.In the hypertext document, the parent chapter just links to the appropriate subchapter wherever it needs to, no matter where the sub-chapter is actually located in the HTML document.

However, when the doc prints, the sub-chapters are often out of sequence, since there is no incentive to put them in any particular order. Hyperlinks can jump anywhere in the doc. For that matter, some sub-chapters may be referenced from several parent chapters, so there isn't a specific "right' presentation sequence. The only issue the hypertext document writer has is to is to make sure that the text is all there somewhere, and that the links are all right. With the printed version, One just has to know how to jump around to the right sections to read it. One could probably re-sequence the "bookmarks' TOC in the PDF doc, to better represent a reasonable reading order, rather than the HTML doc sequence, with some extra work.

There may be similar problems with the other J documentation on the site, since I did all the conversions with a 2-deep hyperlink limit. If anyone spots more problems with the docs, let me know...

It looks to me as if there's something missing, at least with the PDF version of the User Manual. Go to the Regex section; you see the toc for that section. Click on one of the topics (eg, Patterns). The link is to an HTML file Not a part of the pdf document), presumably on Skip's computer: your browser will probably give you a Document Not Found error here.
