Array index starts at 0, not 1, and the size of the first dimension should be 2 and not 1.

string array_check()
{
 string array1[2,4];
 
 array1[0,0]="AA";
 array1[0,1]="BB";
 array1[0,2]="CC";
 array1[0,3]="DD";
 
 array1[1,0]="AA1";
 array1[1,1]="BB1";
 array1[1,2]="CC1";
 array1[1,3]="DD1";
 
 string result=array1[0,1];
 return result;
}

And if I may ask Fernado, what if I wanted to put the array1[0] all inputs in one line?

string array_check()
{
   static string array1[ 2, 4 ] = { { "AA", "BB", "CC", "DD" }, { "AA1", "BB1", "CC1", "DD1" } };
   string result = array1[ 0, 1 ];
   return result;
};

The use of "static" is so that it only initialises the array once and not on every call to the function.
