The string that DisplayAlert() takes is just one big string: dc.b xx , xx , yy , 'this is the string' , 0 , 255 dc.b xx , xx , yy , 'this is the other string' , 0 , 0 So, x and y position. The null terminated string. The continuation byte of 255 on the first line indicates more data to come. The 0 after the second lines indicates the end. There is no need for a pointer, since the next string is right there.
