Lexical function node of a running process

Hi,

In a VMS cluster you can use the lexical functions below to find out if a process is running some where in a VMS Cluster.
The lexical function f$pid gives back the process id.
Is there also a lexical function that gives back the actual node name on which the process is running.

$ PROC_NAME = "PRC_TOINE"
$ ctx = ""
$ tmp = F$CONTEXT("PROCESS", ctx, "NODENAME", "*","EQL")
$ tmp = f$context("PROCESS",ctx,"PRCNAM","''PROC_NAME'","EQL")
$ pid = f$pid(ctx)

Thanks,

/Toine

Well, other than the fact that this approach won't work in other than carefully architected same UIC group environments, and other than that the process name isn't reliable and duplicates have arisen, sure, have at...
