Please give me a hint. set palette file "-" binary record=64 using 1:2:3:4; ????

[Tatsuro MATSUOKA]

Hello 

Please give me a hint for this matter.
Why  " set palette file "-"  " is done in binary mode.

In gnuplot help
      set palette model RGB file "-"

      0 0 1
      0 1 0
      1 1 0
      1 0 0
      e

Can't it be done like that? 

Regards

Tatsuro
