Sorry Mark in my previous post I made an error in the private server
filename which made the example rather pointless.
It should have been this:
$ dir
sys$startup:DECW$PRIVATE_SERVER_SETUP.COM
Directory SYS$SYSROOT:[SYSMGR]
DECW$PRIVATE_SERVER_SETUP.COM;11
Total of 1 file.
The contents were alright.
