TITLE Chapter 5 Exercise 1 (ch05_01.asm)

Comment @Description: Write a program that displays the same string

in four different colors, using a loop. Call the SetTextColor procedure from the book's link library. Any colors may be chosen, but you may find it easiest to change the foreground color.

Assignment 1• Display a null-terminated string and move the cursor to the beginning of the

next screen line (use embedded CR/LF) for the following strings

USAGE of LIBRARY PROCEDURE

Clrscr - Clears console, locates cursor at upper left corner

DumpRegs – Displays general-purpose registers and flags (hex)

WriteChar - Writes a single character to standard output

WriteHex - Writes an unsigned 32-bit integer in hexadecimal format

SetTextColor - Sets foreground and background colors of all subsequent console text output

Assignment 2

• Write a program to display a null-terminated string and move the cursor to the beginning of the next screen line (use embedded CR/LF) as the following output.

• Before proceed to next string, display an unsigned integer 85 in binary, decimal, and hexadecimal, each on a separate line. Please refer the following output.

Use the following variable definition for the remaining questions in this section:

.data

MyByte SBYTE -4,-2,3,1

MyWord WORD 1000h,2000h,3000h,4000h

For the following statements, state whether or not the instruction is valid. Give comment to describe the reason why the instruction become valid or invalid.

mov ax, MyByte

mov ax,MyWord

What will be the value of the destination operand after each of the following instructions executes in sequence?

mov ax, MyWord ; c) ax:______________________________

  mov ax,[MyWord + 2] ; d) ax:_____________________________

  add ax, [MyWord + 2] ; e) ax:_____________________________

By Using PTR keywords, create and complete the following program that can produce the following output based on given variables.

 .data

varB BYTE 65h,31h,56h,65h

varW WORD 6543h,1202h

varD DWORD 87654321h
