TITLE Color String Example              (ColorSt2.asm)

Comment !
Demonstrates INT 10h function 13h, which writes
a string containing embedded attribute bytes to the
video display. The write mode values in AL are:
0 = string contains only character codes; cursor not
    updated after write, and attribute is in BL.
1 = string contains only character codes; cursor is
    updated after write, and attribute is in BL.
2 = string contains alternating character codes and
    attribute bytes; cursor position not updated
    after write.
3 = string contains alternating character codes and
    attribute bytes; cursor position is updated
    after write.
