Someone should do a full audit of everything in the CRTL that uses path names, figure out when and where those path names can be symbolic links and should or should not be followed based on any standards governing the routines in question. I would really like that someone not to be me. I was just curious whether there were other cases that people had run into. >then ask HP OpenVMS Engineering to tell you how they behave with >symlinks, subject to the presence or absence of assorted DECC$ logical >names?

It does sort of look as though the limitations aren't documented consistently, and those that are documented are documented as likely to be lifted in the future. >You mentioned having to define logical names such as >DECC$POSIX_COMPLIANT_PATHNAMES to get certain behaviour from CRTL, but this >runs the risk of breaking other applications.

I'm aware of that capability and have used it before. I'm not sure that'd work for posix-compliant pathnames as you also have to have a root defined, which appears to be a system-wide setting (see HELP SET ROOT). -- ________________________________________ Craig A.
