Panel producer pursues PDF processes
Norbord, an international producer of wood-based panels, runs some of its operations on an HP 3000. This $1 billion company with 13 operating sites around the world needed to create PDFs on its 3000, a task assigned to John Pickering of the company. He went to the 3000 newsgroup for advice on how to do this, working to discover free, online resources already stocked away by indie support companies.
Pickering began by pursuing shareware, which is can sometimes be the budget choice for 3000 shops. (There's a superior and tested PDF-creating solution from Hillary Software, byRequest, which does this for 3000s as well as other enterprise systems.) But if a site wanted to bale together shareware like the txt2pdf software, a manager like Pickering needs Perl to run.
I'd be happy to use the shareware txt2pdf, but I don't know where to begin. The Sanface web site indicates that Perl is required, but that isn't on this 3000, either.
Allegro Consultants, supporting 3000s and crafting MPE software even in 2012, ponied up the Perl that Pickering needed to run txt2pdf.Keven Miller of 3K Ranger, another support provider and consultantcy, put the code for txt2pdf online at his site.
I've placed TXT2PDF.c version 1.1 from Phil Smith onto my site (It's MPE Software item #13) for those that might want to review it.
It's most likely not as advanced as the Sanface product. Probably need to change its name also.
Finally, Robert Mills reported that while he managed 3000s at Pinnacle Entertainment from 2001 to 2008, txt2pdf version 1.1 never gave him many problems in production use.
I had to increase the size of either the pageObs and/or locations arrays, because some of our reports were causing an abort (think that I doubled the size of them).
We didn't have HP's C compiler, so I downloaded GCC and it worked fine. Also, I had some other utilities that were only available in C source, which also compiled and worked when using GCC.
The Gnu C Compiler (GCC) Mills mentioned is the public domain bootstrap software of the 3000's open source software era. It was first forged in the 1990s by Mark Klein, whose DIS International hosts the compiler's software. The latest versions of GCC and related tools may be downloaded from DIS.
An open document format such as PDF was once locked away from HP 3000s until such open source options appeared. We chronicled the other aspects of PDF techniques for HP 3000 use in a story almost two years ago.
The longer that HP 3000s remain online worldwide, the more these updated features will need to be added to the MPE toolbelt. The community is not shy about sharing its experience, and it seems to be well-stocked in what's needed to use open source solutions.
