using idata

hello there.....

my name is hardian, from indonesia

i wrote some code using keil.

the code is :

idata char nim[14] _at_0x00 ;
// i read from the keil textbook (the blue one)


but when i compile it, there's an error message:

missing ';' before '_at_0x00


can u tell me why this is happened ?
or, what should i do with the code ?

thanks very much...

sincerley,
hardian
