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 :confused:

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);

*/

/*

Code:

// 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);

// 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);
