A Simple Adder
In this tutorial we are going to write a some code which assembles a simple addition calculator
MARIEare in string, for example both the variables
valuework in MARIE. Variables are typically declared at the bottom of the code.
The instruction INPUT takes a user input and loads it into the
The main idea is to get the user to input two values and store it into two variables: X and Y. A simple way to do this is:
INPUT Store X INPUT Store Y
This will store the user input into two variables: X and Y. For the purposes we recommend you set the input and output value types to DEC (Decimal) mode.'
The next part requires us to Load X into the AC, then Add Y, output it then Halt the program.
Load X Add Y Output Halt
Now, declare these variables into 'temporary' values, note that declaration is usually at the end of the code.
X, DEC 0 Y, DEC 0
There we have it. The code should something like
INPUT Store X INPUT Store Y Load X Add Y Output Halt X, DEC 0 Y, DEC 0
