The Question is:
What does a RMS_FILEPROT setting of 61440 mean and how would I set the
RMS_FILEPROT so that world or group access would be denied?
The Answer is :
The OpenVMS protection is expressed as a mask. The specified mask
61440 (decimal) is more easily understood as F000 (hexadecimal),
which represents the following protection:
Cleared bits in the mask indicate that read, write, execute, and delete
access, in that order, are granted to the particular category of user.
Bits that are set deny the specified access.
From lowest to highest bit in the word-length mask, each 4-bit nibble
in the protection mask represents system, owner, group, and world access.
System access is open to all accessors possessing a system UIC (any UIC
equal to or less than MAXSYSGROUP) or possessing the system privilege
(SYSPRV) in the currently-enabled privilege mask, owner access to any
user with a matching UIC, group access to any user with a matching UIC
group number, and world access to all other users.
