   '-USSTAB--=--uss_table_name-'   

Specifies the name of a USS table that VTAM® uses to process character-coded input that it receives from the logical unit.

A terminal user can issue a USS command with the LANGTAB operand. This causes a second USS table to be associated with the logical unit, which overrides the table specified with USSTAB. If you do not code USSTAB and a LANGTAB USS table is not in use, the IBM-supplied USS table (ISTINCDT) is used. For more information on USS tables, see Unformatted system services tables.

USSTAB is valid for dependent logical units only.
