    Specifies the parameter kind of a formal parameter. Valid
    keywords are as follows:

    ADDRESS   Specifies that the actual parameter is interpreted

              DEFINE/ADDRESS symbol-name = actual-parameter.
    COMMAND   Specifies that the actual parameter is
              interpreted as a command. Same effect as
              DEFINE/COMMAND symbol-name = actual-parameter.
    VALUE     Specifies that the actual parameter is interpreted as a
              value expression in the current language. Same effect
              as DEFINE/VALUE symbol-name = actual-parameter.
