Twenty-four years ago we started unlocking Hidden Value for HP 3000s: Commands that only the veterans know, plus the processes that have been plumbed to bypass MPE's blind alleys.
Some of the value is specific to a 3000 process like using EDIT/3000. It's antique, that editor, but it's on every HP 3000.
I use cut and paste with EDIT/3000 to enter data to batch files. It works well except that I am limited by the size of the scratch file. Can I change the size of this file so I can paste more at a time?
Immediately after entering Editor, enter "set size=######" to give yourself more space.
For other tasks, like finding forgotten passwords, and keeping them fresh and the 3000's data secret, more elaborate answers have surfaced.
A system manager pitched his plight.
"My operator, in his infinite wisdom, decided to change passwords on manager.sys. Of course he forgot, or fingerchecked... I don’t know. At any rate I need some help. Any suggestions, other than a blindfold and cigarette?"
Several versions of help involved the use of utilities from security experts VEsoft. "Do you have the GOD program on your system? If so, it has PM capability, and so it can give the user who runs it SM capability. So it will allow you to do a LISTUSER MANAGER.SYS;PASS=
(That's why GOD should be secured, by the way. A randomized lockword will do the job, visible only to users who have SM capability. When VEsoft installs MPEX, for example, it installs a randomized password to MGR.VESOFT, and to GOD.PUB.VESOFT.)
Paul Edwards, ever a source for HP 3000 training, ran through the backstop methods every system manager should practice to avoid such a dilemma.
1. You run BULDACCT prior to each full backup so you can look in BULDJOB1 for the passwords
2. You have another user on the system with SM capability and a different password as a backup in case this happens
3. Your operator used LISTUSER MANAGER.SYS;PASS just after changing the password to verify the accuracy as spelled out in the Operations Procedures section in your Systems Manager Notebook
4. You have a Systems Manager Notebook
Then Duane Percox of K-12 app vendor QSS opened up a clever back door:
If your operator can log onto operator.sys:
Using your favorite editor or other utility search for the string: "ALTUSER MANAGER SYS" You will notice: PAS=
, <passwd> which is your clue
