The access authorization is assigned in the definition
file with the APR or APW command.
When a GUD definition file is first activated any
defined access authorization contained therein is
evaluated and automatically re-transferred to the
read/write access of the GUD definition file.
Note
Access authorization entries in the GUD definition
file can restrict but not extend the required access
authorization for the GUD definition file.
Example
The definition file _N_GUD7_DEF contains: APW2
a) The file _N_GUD7_DEF has value 3 as write
protection. The value 3 is then overwritten with
value 2.
b) The file _N_GUD7_DEF has value 0 as write
protection. There is no change to it.
With the APW instruction a retrospective change is
made to the file's write access.
With the APR instruction a retrospective change is
made to the file's read access.
Note
If you erroneously enter in the GUD definition file a
higher access level than your authorization allows,
the archive file must be reimported.
