Lab 1

Lab 1-  After completing this lab we were able to create a program to convert decimal to Roman numerals. The program will also continue to ask users to enter numbers until user enters 0 to exit the program.

program dectorom;
#include("stdlib.hhf")
static
n:int32;
begin dectorom;
stdout.put("Enter a decimal number, ",nl
	     "To exit press 0: ") nl;
  stdin.get(n);
  mov(n,eax);
  while(eax!=0)do

	while(eax!=0)do


  if(eax >= 1000 ) then
      stdout.put("M");
      sub(1000,eax);

      elseif(eax >= 900 ) then
      stdout.put("CM");
      sub(900,eax);

      elseif(eax >= 500 ) then
      stdout.put("D");
      sub(500,eax);

      elseif(eax >= 400 ) then
      stdout.put("CD");
      sub(400,eax);

      elseif(eax >= 100 ) then
      stdout.put("C");
      sub(100,eax);

      elseif(eax >= 90 ) then
      stdout.put("XC");
      sub(90,eax);

      elseif(eax >= 50 ) then
      stdout.put("L");
      sub(50,eax);

      elseif(eax >= 40 ) then
      stdout.put("XL");
      sub(40,eax);

      elseif(eax >= 10 ) then
      stdout.put("X");
      sub(10,eax);

      elseif(eax >= 9 ) then
      stdout.put("IX");
      sub(9,eax);

      elseif(eax >= 5 ) then
      stdout.put("V");
      sub(5,eax);

      elseif(eax >= 4 ) then
      stdout.put("IV");
      sub(4,eax);

      elseif(eax >= 1 ) then
      stdout.put("I");
      sub(1,eax);

            endif;  
  endwhile;
  stdout.put(nl "Enter a decimal number, ",nl
	     "To exit press 0: ")
mov(0,n);
	stdin.get(n);
	stdout.put(nl "You have entered ", n, nl);
	mov(n,eax);

endwhile;

stdout.put(nl, "Program closing."); ;
end dectorom;
