How can I load 256 coeffs one time when I design a IIR filter?

hi ,

       Coeffs are the velue of beta in the red pane in the filter.bmp, I want to use a table to set it , this is ok ?and how can I get it?

        And  I have the other problem about paste, it's troubleful to design a 256 taps IIR filter,   I can design a 184  taps and can't do it any more , a error like error2.bmp will happen,  why?

       thanks
