21 days of radio silence on the 3000-L
The slowing current of 3000 communication showed a fresh signal by the end of this month. As we write it's been 21 days since a message of any kind on the 3000-L MPE newsgroup. The resource that carried 45 messages during last February has 10 for the current month. All of this month's traffic was wrapped around finding resources: Brian Edminster of Applied Technologies and Vesoft support. Both were located.
However, the three weeks without a new message is new territory for the community's log of technical help and outreach by cohorts. Among those who were posting during 2015, several told us they're on the mailing list-newsgroup out of habit — rather than needing details for their datacenter's 3000s.
"I’m still on the list out of inertia, nostalgia and mild interest," said Dave Heasman, a UK IT manager. "My employer got rid of their 3000s and me in 2008. Bought a series of packages to replace a big bespoke brokerage/investment system."
Robert Mills said he "remained a member of the list, mainly as a lurker, to keep appraised of what was happening in the 3000 community. Except for three requests in September 2012, December 2014, and February 2015, I've only posted to the list when I felt that the 3000 knowledge I had would help somebody solve a problem." Mills said he retired when his company went insolvent in 2009, but he's kept his hand in IT.
"I have been involved with the GnuCOBOL (formerly OpenCOBOL) Project on SourceForge since October 2014, and decided to write a macro preprocessor that emulated the functionality available on the 3000," he said. "The preprocessor, CobolMac, is now in its 5th version (B.04) and has received good reviews by its users."
Others who contacted us said they haven't worked on the 3000 since the days that HP sold support for MPE/iX. "I have been a BizTalk developer full time since 2008," said Kent Wallace. "I needed to work, and this was the direction the world was going." The 3000-L still has more than 500 subscribers on its mailing list rolls, but much of the messaging comes from consultants and vendor experts, supplying answers to questions and tips. A total of 45 messages have passed through the list since the start of 2016. The IT pros like Wallace have taken the path to other platforms, first to HP-UX, then to Windows.
"I left my previous employer in Boise and I moved to a Microsoft shop, whose mainframe was HP-UX," Wallace said. "However, in 2015 we migrated off HP-UX and onto SQL Server on Microsoft Server 2008. We do health insurance and the purchased software, Trizzeto, was moved to MS SQL servers."
Another registered user keeps up with the community, but he can imagine a future where he'd be back on the MPE/iX front lines. "We're totally out of the 3000 business," said Ted Johnson of Wake Forest University, adding a sad-face emoji. "But I love seeing the 3000-L posts and keeping up. Who knows — maybe they'll get rid of me one of these days, and I'll end up back on a 3000."
The 3000-L, hosted at the University of Tennessee at Chattanooga where the late Jeff Kell launched it the early 1990s, holds more than two decades of traffic. 10 years ago the list was big enough to measure a signal-to noise-ratio, but by now it's almost entirely signal. When John Burke was a monthly columnist for the NewsWire who summarized its content in net.digest, he rounded up the following help in just one month's communications. For a 3000 owner managing a homesteading shop, the 3000-L's tips still carry some value.
• Do you want to know when a particular account or group was created? LISTACCT and LISTGROUP are no help. But “listfile /ACCOUNTNAME,3” for the account or “listfile /ACCOUNTNAME /GROUPNAME,3” for the group tell all. And then some.
• The number of sectors reported by the REPORT command for a group or groups is sometimes inaccurate, sometimes very inaccurate. Running the program FSCHECK.MPEXL.TELESUP and issuing the SYNCACCOUNTING command will fix this problem.
• In case you were wondering, despite many requests for the enhancement, TurboStore will NOT append store sets to tape. Well, it might if you use the proper incantations, but it is unsupported and highly dangerous because under certain circumstances you could overwrite a previous backup without knowing.
• Speaking of things you cannot do that you might like to do, the ALLOW command is not persistent across sign-ons unless you use the extremely dangerous “ALLOW @[email protected]; commands” version. This is another example of an enhancement that has been requested for years, but now will never happen. Fortunately, there are a number of options, for sale and free (MPEX, CSL, etc.).
• CI integer variables are signed 32-bit entities. So be careful if you are doing some wild arithmetic in your CI scripts.
• Here is a little trick when using Apache’s indexing (for example to keep track of documentation) to index file displays. You can override the default ascending sort by name by appending “?N=D” to the url. Instructions on changing Apache’s default behavior are available on the Web.
• If you are trying to program VPlus applications and are interested in working examples programmed in your favorite language, look in the group HP32209.HPPL89 (which should be on every FOS tape). This group contains source code for the ENTRY program in a variety of languages including COBOL, Fortran, Basic and Pascal.
• To see the firmware (aka PDC) Revision of a system (CPU): Run cstm, and at the cstm > prompt, type ‘map’ and note the Dev Num of a CPU and then type ‘sel dev DEV_NUM’ (e.g., ‘sel dev 41’) and then type ‘info’ and then type ‘il’ and look at the output for the ‘PDC Firmware Revision’. Easy, huh? Thanks to Guy Paul of HP for this tip.
• SPFXFER will allow you to write to disk (undocumented “feature/bug”). But don’t do it, because SPFXFER cannot read the disk file it creates! Doing this could lead to a big oops.
• While it would certainly be a nice to have, MPE/iX CI scripts have no provision for inline comments. Sorry, don’t even bother trying.

It is sad if interest is waning. I hope people are simply on vacation, or they already know all the answers.
Now, there are quite a few things people could help me with, but when I put something out there, there is a flurry of short responses, and sometimes these are helpful, but then interest in responding wanes.
At the same time, MPE work is not my full-time job, so I do not always get around to asking what I would like to ask.
In some responses, a vendor informs of his commercial software that would fix my problem, without anyone having to do much. Those are not short-term fixes, even if we did have the money to spend on them.
There have been other slow periods, but I believe it will pick up again, particularly when that company announces the launch of Lindows, which will be a Windows-like interface running on Linux (as a client) which will use Posix 7.5
on a Stromasys box as the underlying server and DBMS.
