        XBC  value1 [ operation value2 ] [/output-type] [R]

            -Value1/2:  [type]digit.
               type: z:decimal, x:hexadecimal, o:octal, t:hhmmss.xxx fmt.
               Decimal is up to 19 digit,and may contain seperator ",".
               If type is ommitted,decimal when all digit is 0 to 9,
               hexadecimal when all is valid hexadecimal digit,
               t when hh:mm:ss format.
               After decimal point,up to 9 digit is allowed,but for x
               and o,decimal fraction is not supported.
               For double word, concatinate 2 word hex-decimal by ".."
               like as abcded01..23456789.
            -operation:  +,-,*,!,/,%,  <,>,|,&,^.
               ('!':power, '<','>':shift, '^':exclusive OR.)
               Shift or bit operation is not valid for time.
               If operation missing,do base conversion.
               Opearnd with type!=t is treated as seconds when calculated
               with time operand.Multiply and divide between times is also
               by the value of seconds.
               Doubleword precision is for +,-,*,/,% only.
               Overflow is move up to doubleword precision for decimal calc,
               or ignored for octal/hex calc.
            -output-type:result display type.
               x:hexadecimal, o:octal, d:decimal, u:unsigned decimal,
               z:decimal by zzz,zz9, uz:unsigned decimal by zzz,zz9,
               t:hh:mm:ss.xxx edit fmt,
               l(lower L):convert to clock from a word(seconds from 1970)
               or double word(Mainframe TOD.In double word bit 51 is
               unit of micro second).
               When mainframe HOST-TOD is before 2000/01/01,
               it is displayed as elapsed second from 1900/01/01.
               If ommitted,hexadecimal for decimal,decimal for octal
               and hexadecimal and number of second for type=t.
               Result of divide for decimal,precision is 1 up.
               for x or o,residual is displayed.
            -R:leave result string on to the cmd input line to use as
               next XBC cmd input.
          (ex) XBC T010100 ; XBC xfe0100  ; XBC o177 ; XBC e8ff>3
               XBC T012159.12+t005212.333 ; XBC xabcdef+1000
               XBC 12345678..abcdef0/30a2 ; XBC 3acf19fe/l
