The HP 3000 has a healthy range of open source tools in its ecosystem. One of the best ways to begin looking at open source software opportunity is to visit the MPE Open Source website operated by Applied Technologies. If you're keeping a 3000 in vital service during the post-HP era, you might find perl a useful tool for interfacing with data via web access.
The 3000 community has chronicled and documented the use of this programming language, with the advice coming from some of the best pedigreed sources. Allegro Consultants has a tar-ball of the compiler, available as a 38MB download from Allegro's website. (You'll find many other useful papers and tools at that Allegro Papers and Books webpage, too.)
Bob Green of Robelle wrote a great primer on the use of perl in the MPE/iX environment. We were fortunate to be the first to publish Bob's paper, run in the 3000 NewsWire when the Robelle Tech long-running column made a hit on our paper pages.
You could grab a little love for your 3000, too. Cast a string of perls starting with the downloads and advice. One of HP's best and brightest -- well, a former HP wizard -- has a detailed slide set on perl, too.
An extensive PowerPoint presentation on perl by the legendary porter Mark Bixby will deliver detailed insights on how to introduce perl to your programming mix. Bixby, who left HP to work for the 3000 software vendor QSS, brings the spirit of open source advocacy to his advice on how to use this foundational web tool.
As an example, Bixby notes that "it's now possible to write MPE applications that look like web browsers, to perform simple HTTP GET requests, or even complicated HTTP POST requests to fill out remote web forms." It's no box of Godiva, or even the classic blue box from Tiffany's, but perl might be something you love to use, to show that 3000 isn't a tired old minicomputer -- just a great sweetheart of a partner in your mission-critical work.
