Hi Greg, Yes, I hadn't realised initially that the issue had already been discussed before (and not fixed). You'll find that that "upvar" and the link above has since been mentioned in this thread (see also https://www.mail-archive.com/bug-bash@gnu.org/msg19445.html) At this point, I have little hope that bash will be fixed. But mksh/oksh and yash still might. -- Stephane
