Just do it like this and then it will work:
Code: | void main()
{
int8 varia[2] ={5,45};
int8 knife;
knife = varia[1];
while(1);
} |

At compile time the comlier only works with literals, knows nothing about what are in "PIC memory".
Why not use a #define VAL 45
then varia[2]= {5, VAL}
int8 knife=VAL

Thanks PCM and Alan for your kind help. Everything worked fine now. Just to let you know that the first time I forgot to put the the routine in function. But now it ok.
To make the second step, I am creating two arrays such below. I am right if i say that if I create two-dimensional array I can increment the first coordinate [i] to load the second array in the memory?
Code: | int8 alarm[1][7] = {11,7,14,4,0,6,05};
int8 alarm[2][7] = {11,7,14,4,0,8,05}; |
Thanks |

No, you don't initialize a 2-dimensional array like that. Do it like this:
Code: |
int8 alarm[2][7] = {
{11,7,14,4,0,6,05},
{11,7,14,4,0,8,05},
};
