on disk, blanks are returned.
An unqualified form of the file owner's name is returned as the value of this
itemnum . The file owner is not neccessarily the file's creator. File ownership may
be changed using the :ALTFILE command.
A symbolic zero (ASCII 48 in decimal) is returned as the file owner for root
directories, accounts, and MPE groups created prior to release 4.5 of MPE/iX.
If the file is not located in the account in which the file owner is a member, a
