To implement a program that computes the factorial of a numbers.
The program to compute the factorial and its equivalent low-level instructions executed by the hardware. The low-level instructions used are:
| assign | It assigns a value to a variable |
| load | It loads a value of a global or local variable to the given register |
| store | It stores the value from the given register to the global or local variable |
| out | It prints the output value to the screen. |
| in | It reads the input from to user and stores in a variable |
| incr | It increments a register value by 1 |
| mul | It multiplies the values contained in two registers and puts the result in the first register. |
| lte | Check if the value in the first register is less than or equal to that of second register. |
| if_true | Checks if the condition evaluated to true. |
| if_false | Checks if the condition evaluated to false. |
| label | Is used to mark the position in the low-level instructions to enable jumping to the marked position. |
| exit | Signifies the end of program |
