Hi Costas,

It depends on what you are referring to.... If you talking about disc
structures used to house the data you are essentially correct.  However,
information about the location of permanent files is maintained in
system directory structures while information on temporary files is
maintained in a job/sessions's JDT, or Job Directory Table in an area
called the Temporary File Directory.  This is why they are only known
to the particular job yet can be shared by all child processes launched
from the job/session's CI process. When a job/session terminates
(logs-off), it is the TERMINATE() procedure which walks the Temporary
File Directory in the JDT and basically 'deletes' the files from disc
storage.

Yes, and it is also possible to build temporary files in groups in other
accounts and manipulate them as well.  Only you cannot save them as
permanent files unless you have appropriate authorization, such as SM
capability.  By the way, there really is a 'Save File' security attribute
at the account level, only MPE commands do not reveal it, setting it to
"AC" by default when an account is created or security access altered.
What this means is an exercise I'll leave for the reader.... ;-)
