The translation attributes of a logical name determine how its translation is handled at various times.
If a logical name’s translation is specified as “CONCEALED”, its translation is not displayed unless that is specifically requested.
If a logical name’s translation is specified as “TERMINAL”, no further attempt is made to translate the current translation of the logical name. This is used in some CONCEALED logical names. It was also used in early VAX systems to reduce the machine time requirements for translation of logical names.
