Thread: Problem: 64k block issue

Hello guys n gals, here I have 4 case situations which I have tested using this compiler, however only Test #1 works.

The issue is related to far and near 64k data blocks.

In general I am trying to copy data from the far to near and vice versa, with no success so far.

See if you can see the what problem is, I can't

Code:

// Definitions
byte         response_string[300];
byte far    far_response_string[3500];
byte	*near_ptr;	/////
byte	*near_ptr2;	/////
byte far	*far_ptr;		/////	
byte	near_array[5];	/////

/*

Code:

// Test 1: copying the contents of near pointer into contents of another near pointer
	
	near_array[0] = 0;
	
	strncpy( near_array, "hi", 3 );
	near_ptr2 = &near_array[1];
	near_ptr = &response_string[0];
	*near_ptr = *near_ptr2;
	clear_lcd();	sprintf( _temps, "%c", response_string[0] );	puts_lcd( _temps );	delay(3000);

*/

/*

Code:

// Test 2: copying the contents of far pointer into contents of near pointer
	
	far_response_string[0] = 0;
	
	_fstrncpy( far_response_string, "hi", 3 );
	far_ptr = &far_response_string[1];
	near_ptr = &response_string[0];
	*near_ptr = *far_ptr;
	clear_lcd();	sprintf( _temps, "%c", response_string[0] );	puts_lcd( _temps );	delay(3000);

*/

// Test 3: copying the contents of far pointer into near array
	
	near_array[0] = 0;
	
	_fstrncpy( far_response_string, "hi", 3 );
	far_ptr = &far_response_string[1];
	near_array[0] = *far_ptr;
	clear_lcd();	sprintf( _temps, "%c", near_array[0] );		puts_lcd( _temps );	delay(3000);

/*

Code:

// Test 4: copying the contents of an indexed far array into index near array
	
	far_response_string[0] = 0;
	
	_fstrncpy( far_response_string, "hi", 3 );
	near_array[0] = far_response_string[0];
	clear_lcd();	sprintf( _temps, "%c", near_array0] );	puts_lcd( _temps );	delay(3000);

Here's an idea! Get a real compiler. Stop using Turbo C 3.0 or whatever ancient thing you're working with, and get a real compiler.

Quzah.
