  3. RE: Logon to only a specific workstation.
     (Martin, Steve (MAN-Golden))

One way I've seen it done, is to use a file of at least 2 fields, UserID &
WorkStn. Create a program that retrieves the user profile and workstation,
then does a lookup in the file. If the UserID exists, and workstation ==
WorkStn, then continue.

Use the new program as the INLPGM in each user profile you want to control.

(Hi, Steve.) Suggestions to use an exit program might be reasonable, but be extremely careful if you're writing your own. It's necessary to understand critical details of the structures being passed because it's easy to make at least one specific minor mistake which will throw your system wide open.

Authorization lists have also been suggested and can be an excellent control mechanism. But it can get loose when auto-config creates new devices. They take maintenance and it takes thought on setting them up well in the beginning. Not exactly rocket science, but forethought makes a difference.

Now, an INLPGM has its own merits; however, I'd go with a routing program instead. The program itself could be an almost exact copy, but it'd apply to everyone without needing to update individual profiles nor would it interfere with any existing INLPGM.

The major logical difference between a routing program and an INLPGM for this purpose would be that the routing program would end with a statement like TFRCTL QSYS/QCMD instead of just a RETURN.

In the default case, use the CHGRTGE command to change the 9999-*ANY and/or the compare value 'QCMDI' routing entry in QINTER to name your program instead of QSYS/QCMD. Reapply as needed after upgrades.

If the program contains essentially nothing but the TFRCTL command, you shouldn't even notice a defference. Add a SNDMSG command before TFRCTL and you have a trivial program that demonstrates how it works without being intrusive (unless you reference a message queue that the user has insufficient authority for or some other problem without handling the error). And once the program's in place, you can use it for a number of purposes; I commonly use mine to pop-up bulletin windows at signon when news needs to be sent -- "Shutdown at 2:00 PM today", e.g.
