Glossary
absolute pathname A pathname that begins with the root directory, such as
/SYS/PUB/TDP. See also pathname and relative pathname.
access control definition (ACD) Security feature that controls access to files and
directories. Consists of a list of access permissions and user specifications. (For example,
R,W,X:@.PAYROLL gives all users in the PAYROLL account read, write, and execute access to
the file or directory that is assigned this ACD.) ACDs are applied to files or directories by
using the ALTSEC command. By default, all files existing outside the traditional MPE
account/group structure and all directories are assigned ACDs when they are created.
access mode A type of access permitted to a file, such as write, read, or execute access.
appropriate privilege Having sufficient capabilities to perform an operation on MPE/iX.
SM capability always provides appropriate privilege to system administrators.
archiving Storing infrequently used or out-of-date files onto tape and permanently
removing them from the system disks at the same time.
back reference The technique of using an asterisk (*) before a formal file designator to
indicate that it has been previously defined during the current session or job with the FILE
command.
backup The process that duplicates computer data to offline media, such as a magnetic
tape. Backups protect data if a system problem should occur.
backup devices System peripherals that allow you to write information to, and read
information from, backup media.
case sensitivity HFS filenames can be saved in uppercase or lowercase letters. The file
named ./FILE1 does not refer to the same file as ./file1 or ./File1.
character A letter, number , or symbol represented by one byte of data.
character set A series of characters to substitute for a single character to name a group
of files.

utility program to perform a specific operation.
compatibility mode(CM) Compatibility mode provides object code compatibility
between MPE V/E-based systems and the 900 Series HP 3000. Compatibility mode allows
current Hewlett-Packard customers to move applications and data to the 900 Series HP
3000 without changes or recompilation.
