2. Chess Board Write a program that draws an 8 8 chess board, with alternating gray and white squares. You can use the SetTextColor and Gotoxy procedures from the Irvine32 library. Avoid the use of global variables, and use declared parameters in all procedures. Use short procedures that are focused on a single task.

I already have Exercise 2, just need the second part please!

INCLUDE Irvine32.inc ; procedure prototypes: SetColor PROTO forecolor:BYTE, backcolor: BYTE WriteColorChar PROTO char:BYTE, forecolor:BYTE, backcolor:BYTE PrintRowOdd PROTO color:BYTE PrintRowEven PROTO color:BYTE

.data rows = 8 columns = 8 horizCharsPerSquare = 2

.code main PROC mov ecx, rows / horizCharsPerSquare L1: INVOKE PrintRowOdd, gray call Crlf INVOKE PrintRowEven, gray call Crlf loop L1

INVOKE SetColor, lightGray, black ; return to normal color call Crlf

exit main ENDP

PrintRowOdd PROC uses ecx, color:BYTE mov ecx, columns / horizCharsPerSquare L1: INVOKE WriteColorChar, ' ', color, color INVOKE WriteColorChar, ' ', color, color INVOKE WriteColorChar, ' ', white, white INVOKE WriteColorChar, ' ', white, white loop L1

ret PrintRowOdd ENDP

PrintRowEven PROC uses ecx, color:BYTE mov ecx, columns / horizCharsPerSquare L1: INVOKE WriteColorChar, ' ', white, white INVOKE WriteColorChar, ' ', white, white INVOKE WriteColorChar, ' ', color, color INVOKE WriteColorChar, ' ', color, color loop L1

ret PrintRowEven ENDP

WriteColorChar PROC USES eax, char:BYTE, forecolor:BYTE, backcolor:BYTE INVOKE SetColor, forecolor, backcolor mov al, char call WriteChar

ret WriteColorChar ENDP

SetColor PROC, forecolor:BYTE, backcolor:BYTE movzx eax, backcolor shl eax, 4 or al, forecolor call SetTextColor ; from Irvine32.lib ret SetColor ENDP END MAIN

This exercise extends Exercise 2. Every 500 milliseconds, change the color of the colored squares and redisplay the board. Continue until you have shown the board 16 times, using all possible 4-bit background colors. (The white squares remain white throughout.)
