RE: full system save. Option 21 -- MIDRANGE-L

Dan

yeah you still need to sign on, although I suppose you could acquire the 
device as discussed in a separate thread - I don't like this idea for the 
console though.

My observation of BRMS was that it kicked off a program that then just 
waited on a data queue (QRCVDTAQ with a timeout of  -1  (wait forever 
(corrections accepted :))))

Additionally you could interrupt it by signing back in - I presume it 
either checked two dataqueues cycling between them, or alternatively the 
"signing back in" action caused a return to screen control entry to be 
placed on the dataqueue. In other words, the BRMS screen displays an option 
on the console to allow you to interrupt processing at the console - an 
important feature in my mind !

I've made that sounds more complex than it seems, and no doubt someone more 
knowledgeable about BRMS will correct me or add to the discussion.

I have been meaning to get around to this for quite a while (i.e. adding 
the console wait on data queue function to my save programs), but the first 
thing I need to add (like BRMS appears to have - can someone confirm ?) is 
the ability to prevent break messages that arrive on the console 
interrupting processing. This is in fact the major reason I haven't 
progressed this

On this topic - how WOULD you ensure that a screen waiting on a dataqueue 
"ignored" or otherwise handled break messages. My own initial 
experimentation with RCVMSG was fruitless, though I did not spend a lot of 
time on it.

Hope this provides more food for thought
