Well, I got to pull out my old System/370 reference "green card" (really a yellow book) for the first time in quite a while. That was quite nostalgic.
The reason for using it isn't quite as much fun, though. I'm trying to get the Xymon client for VM working, which uses WAKEUP. I haven't used that in a number of years and am running into a weird problem. It will work for hours without a problem and then just drop out of WAKEUP due to an "external interrupt". WAKEUP is being called as follows: WAKEUP +5 ( CONS EXT SMSG FILE(HOBBIT TIMES *) Sometimes, it will run through a sequence and then exit, sometimes it will run for several days before it happens. This is happening on different systems to, not just on one VM system. I suspect that some silly thing is not set correctly, but I have no idea what. I finally did a CP TRACE EXT on one of them and found that it is getting an external interrupt code 1004. According to my trusty old reference book, that is a "clock comparator" interrupt. That is what is causing WAKEUP to stop with RC=6. Any ideas on how I can get it to stop doing that? Martha
