- Just curious, from which version of VMS did you upgrade to V5.5-2?
- The reason I ask is that we are running V5.5-1 and I ran into essentially
- the same problem: subprocess unable to access the drive allocated to the
- parent (don't take me too literally, can't remember whether the drive
- was mounted or just allocated...). This had nothing to do with BACKUP.
- I just gave up without thinking much more about it :-(
