key-table-id

    OpenVMS usage:identifier
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference

    Specifies the key table from which you are extracting a
    definition. The key-table-id argument is the address of an
    unsigned longword that contains the key table identifier.

    The key table identifier is returned by SMG$CREATE_KEY_TABLE.

 key-name

    OpenVMS usage:char_string
    type:         character string
    access:       read only
    mechanism:    by descriptor

    Specifies the name of the key associated with the definition. The
    key-name argument is the address of a descriptor pointing to the
    key name.

 if-state

    OpenVMS usage:char_string
    type:         character string
    access:       read only
    mechanism:    by descriptor

    Specifies the current state name in effect after the key is
    pressed. The if-state argument is the address of a descriptor
    pointing to the state name.

    See SMG$ADD_KEY_DEF for more information.

 attributes

    OpenVMS usage:mask_longword
    type:         longword (unsigned)
    access:       write only
    mechanism:    by reference

    Receives the attributes bit mask for this key definition. The
    attributes argument is the address of a longword into which is
    written the bit mask describing the key's attributes.

    Valid values are as follows:

    SMG$M_KEY_NOECHO   If set, this bit specifies that equiv_string
                       is not to be echoed when this key is pressed.
                       If clear, equiv_string is echoed. If SMG$M_
                       KEY_TERMINATE is not set, SMG$M_KEY_NOECHO is
                       ignored.
    SMG$M_KEY_         If set, this bit specifies that when this key
    TERMINATE          is pressed (as qualified by if-state), the
                       input line is complete and more characters
                       should not be accepted. If clear, more
                       characters may be accepted.
    SMG$M_KEY_         If set, and if state-string is specified, the
    LOCKSTATE          state name specified by state-string remains
                       at the current state until explicitly changed
                       by a subsequent keystroke whose definition
                       includes a state-string. If clear, the state
                       name specified by state-string remains in
                       effect only for the next defined key stroke.
    SMG$M_KEY_         If set, this bit specifies that this key
    PROTECTED          definition cannot be modified or deleted.
                       If clear, the key definition can be modified
                       or deleted.

 equivalence-string

    OpenVMS usage:char_string
    type:         character string
    access:       write only
    mechanism:    by descriptor

    Receives the equivalence string for this key definition. The
    equivalence-string argument is the address of a descriptor
    pointing to the string into which is written the equivalence
    string.

 state-string

    OpenVMS usage:char_string
    type:         character string
    access:       write only
    mechanism:    by descriptor

    Receives the new state name, if any, which is set by this
    key definition. The state-string argument is the address of a
    descriptor pointing to the string into which is written the new
    state string.
