POSTDEC1,2 error in simulator ?!

[yo2lio]

HI,

This code work ok in simulator (move string right with one position ...):

Code: Select all

  data1 := '1234';
  FSR1Ptr := @data1 + 3;
  FSR2Ptr := @data1 + 4;
  while true do POSTDEC2 := POSTDEC1;

Just changing FSR1Ptr with FSR2Ptr and POSTDEC1 with POSTDEC2, in simulator string will be null !

Code: Select all

  data1 := '1234';
  FSR2Ptr := @data1 + 3;
  FSR1Ptr := @data1 + 4;
  while true do POSTDEC1 := POSTDEC2;

I don't know yet it's code problem (hex) or simulator problem ...

I do not know where the problem is, it is maybe because we are using FSRxPtr inside compiler, we never intended it to be use by a user...

I think, the problem it's possible to be in simulator .

Tested in MikroC and i found same problem. This code work ok :

Code: Select all

char data[] = {1,2,3,4,0} absolute 200;

void main(){
  FSR2H = 0;
  FSR2L = 204;
  FSR1H = 0;
  FSR1L = 203;
  while (1) {
    POSTDEC2 = POSTDEC1;
  }
}

This code no :

Code: Select all

char data[] = {1,2,3,4,0} absolute 200;

void main(){
  FSR1H = 0;
  FSR1L = 204;
  FSR2H = 0;
  FSR2L = 203;
  while (1) {
    POSTDEC1 = POSTDEC2;
  }
}
