Code isn't jumping correctly

I'm currently trying to do my assignment but I'm having some issues.

This is the assignment

https://i.sstatic.net/7KRAL.png enter image description here

As it is right now, When I put 'CC' I only get back 

Feed me(2 hex digits with the bits prsseeee):CC
Fall Semester
Total Fees = $ 97

When I should be getting back 

Feed me(2 hex digits with the bits prsseeee): CC 
Fall Semester 
12 units 
CA Resident 
Parking 
Total Fees = $ 688

Here is what I've done so far.

I'm also only allowed to use

so far

program SMCFee;
    #include( "stdlib.hhf" );
    static
        total : int32 := 0;

begin SMCFee;

    stdout.put("Feed me(2 hex digits with the bits prsseeee):" );
    stdin.get(BL);

    ror(4, BL);
    and(%0000011, BL);

    cmp(BL, %00);
    je Fall;
    cmp(BL, %01);

Solution

  • I think you had a few errors:

    Learning to handle binary values is initially un-intuitive.

    These are pretty typical errors of green assembly language programmers. Getting past them to a running program really helps build confidence. Do a lot more of this, you'll be pretty good at it.

    Learn to mentally simulate your code. This pays off like gold.
