It gives the error because it expects arrays as parameters but it founds integers:

pawn Код:

function610(arg0[], arg1[])

Nonetheless, I believe you want this function to copy a string to another but you can use strcat for that:

pawn Код:

#define strcpy(%0,%1) strcat((%0[0] = '\0', %0), %1)

and an example:

pawn Код:

new
    string[5],
    string2[5] = "test";

strcpy(string, string2, 5);

string now holds "test" too.
