[Sdcc-user] XBYTE problem solved !!

[<sdc...@ya...>]

Hi,
I was able to pass the address using variable to
the XBYTE instruction for storing value at that 
particular location.

Here is my Code :-)))
karthik.c
=========
#include<stdio.h>
#include<8051.h>
#define XBYTE *(xdata unsigned char *)
unsigned char _sdcc_external_startup()
{
return 0;
}
void main(void)
{
xdata km;
km=0xA000;
while(km!=0xA00f)
{
XBYTE(km)=0x0004;
km++;
}
}

THus i was able to store 0x0004 in the locations
starting from 0xA000 to 0xA00f.

The Point to be Noted - I declared the variable 'km'
as xdata type. If u declare that 'km ' variable
'as unsigned char km' or 'xdata unsigned char km', u
will not get the value stored at that particular
address even though the program gets compiled 
correctly. 

A small declaration problem .
