Instructions I

Potentially useful functions:

• string-contains?
• string-split
• substring
• string-replace
• string-append

Optional:

• Package: match-string

Goal

We want to be break a instruction string into three separate pieces: the destination, the operation, and the jump/comparison.

• Destination: the register(s) where the result goes.
• Operation: the computation performed by the ALU, like A+1 or M&D.
• Jump comparison: JMP, JLE etc.

Your end goal is to take in an instruction string and produce a list of strings with three components: (list destination operation jump).

Warmup

Write examples of what should be produced in these situations:

1. DM=M+1;JMP
2. A=D-1
3. M=0
4. D;JLE
5. 0;JMP

Write two more examples that you make up.

Coding

Turn your examples in check-expects.
