Maybe fill an array with the characters. The array only would hold a pointer to a string, though. Then loop through the array and loop inside the loop again to add a second letter. Something like:

Code:

---

var ArrayOfChars[6];

..

function SetupChars()
{
ArrayOfChars[0] = str_create("A");
ArrayOfChars[1] = str_create("a");
ArrayOfChars[2] = str_create("B");
ArrayOfChars[3] = str_create("b");
ArrayOfChars[4] = str_create("1");
ArrayOfChars[5] = str_create("2");
}

var i;
var k;

string first;
string second;
string final;
	

function CreateWords()
{
	while(i != 6)
  	{
   	while(k != 6)
   	{
   		first = ptr_for_handle(ArrayOfChar[I]);
   		second = ptr_for_handle(ArrayOfChar[K]);
   		str_cat(first, second);
   		//so something with final word combination
   		final = first;
   		k += 1;	
		} 
		i += 1;
  	}
}

---

This is not tested (may not work), and straight of the top of my head. It is probably not a very good method, either. If you were using a long list of different characters it might be better to work with ASCII numbers and convert them back into strings rather than use strings straight off..

Hope it helps,
