| strange behavior of int32 Array |

Hi,
I have a problem using int32 arrays. I want to load an array each time #int_ext is executed. Then, I print it pressing RB7.
If I use a variable as index as in program below it doesn't work.
| Code: |
Index=4;
Values[Index] = 0x1;
|
it complete Values[3]=65536 instead of Values[4]=1.
but, when I use a numeric index directly is works ok.
With int8 arrays it works fine. Any suggestions ?
ps. Im using PIC18F452 and CCS 3.249.
thanks
