Wouldn't the HL7 link monitor be an example of this? The background processes write something about their state to a global and some other process monitors the global and displays it. Depending on how precise you need to be, you could use $J as a subscript and you won't need to lock.

I hadn't thought of it when I replied here, but his solution can be made to work using $INCREMENT S ^GLOBAL=0 J1 ; F I=1:1:100 S ^GLOBAL($INCREMENT(^GLOBAL))="A" Q J2 ; F I=1:1:100 S ^GLOBAL($INCREMENT(^GLOBAL))="B" Q I still can't think of any way to do it in Standard MUMPS. === Gregory Woodhouse [EMAIL PROTECTED] "The whole of science is nothing more than a refinement of everyday thinking." -- Albert Einstein ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
