ACCESS ACCESS Use the ACCESS command to identify a disk to CMS, establish a filemode
letter for the files on the disk, and set up a file directory in
storage. The specifications of the ACCESS command determine the entries
in the user file directory. The format of the ACCESS command is: r- --, , , r .. , , ACcess , cuu moder/ext [fn [ft [fm]]]] [ (N 0 PRO F [) ]] I , , , 121 * * * I I , , 1 I , , cuu mode (ERASE [)] , , , , , , , , (NODISK [) ] I I I I L JI , L -JI cuu makes the disk at the specified virtual device address
available. The default value is 191.
Valid addresses are 001 througn 5FF for a virtual machine in
basic control mode, and 001 through FFF for a virtual machine
in extended control mode.
mode assigns a one-character filemode letter to all files on the
disk being accessed. This field must be specified if cuu is
specified. The default value is A. ext indicates the mode of the parent disk. Files on the disk
being accessed (cuu) are logically associated with files on
the parent disk; the disk at cuu is considered a read-only
extension. A blank must not precede or follow the diagonal
(/) .
fn [ft [fm]] NOPR:)F ER ASE NJDISK defines a subset of the files on the specified disk. Only the
specified files are included in the user file directory and
only those files can be read. An asterisk coded in any of
these fields indicates all filenames, filetypes, or filemode
numbers (except 0) are to be included. (See Usage Notes 3 and
4.) If a fi lemode is specified, it must be specified as a
letter and a number. For OS and DOS disk access restrictions,
see Usage Note 9.
suppresses execution of a PROFILE EXEC file. This option
is valid only if the ACCESS command is the first command
entered after you IPL CMS. On subsequent ACCESS commands, the NOPROF option is ignored.
specifies that you want to erase all of the files on the
specified disk. This option is only valid for read/write
disks. (See U sage Note 7. lets you gain access to the CMS operating system with no
disks accessed except the system disk (S-disk) and its
