The program convert arabic numbers into roman numbers and vice versa.
First Str1 and Str2 are defined and 1000->M, 500->D, 100-> C, 50->L, 10->X, 5->V and 1->I

After that you input your number (arabic or roman)
It compares each characters of your number to Str2. 
If one of them isn't in Str2 it output INVALID and the invalid character.

Next it look at your number and find if it's an arabic or roman number. 

If it's an roman number it changes your number into an equation and 
with the definded letters it add each number and output the equal arabic number.

If it's an arabic number it breaks up your number. 
First it find how many thousand and change the number into letters. 
Next the hundred, the ten and the units. At the same time it looks 
for each 4 and 9 in your number and it changes the letters in consequence. 
(ex : 14 is XIV but 4 is 4 units so 4 is IIII then when there is a 4 or 9 it changes the letters)
Finally it stores the roman number in a new Str and output it.
At the end it deletes all the Str used in the program.

Use this program as you want but don't change it
Do not separate this document of the program.
