Creating a Unix File

Hi,

I have an internal table i_tab1 which contains both characters and numerics, when i use the following statement, I am getting an error saying T_TEXT and I_TAB1 are not mutually convertible in an Unicode program.

data: t_text(1000) type c.

data: begin of i_tab1 occurs 0,

field1(10) type n,

field2(10) type c,

end of i_tab1.

APPEND i_TAB1.

MOVE I_TAB1 TO T_TEXT.

TRANSFER T_TEXT TO P_FIOUT.

Does anyone know how i can solve this?
