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

idata char nim[14] _at_0x00 ;

You need a space before and after the _at_ keyword. Re-written for correctness:

char idata nim[14] _at_ 0x00;
Yes the idata goes in between the char and the nim if you want to be current with Keil C51 although idata char nim will still work.

Of course you will trash register bank 0 and part of register bank 1 with nim[] located at 0x00, move nim[] up to at least 0x08 and read Intel's MSC-51 User's Manual (it's on their website).
