Observed
Line 14 of src/multiplyTwoNumbers.asm reads:
The comma between the second and third operands is absent. Every other three-operand instruction in the file separates all of its operands with commas:
8: AND R1, R1, #0
9: AND R2, R2, #0
10: ADD R1, R1, #5 ; store five in R1
11: ADD R2, R2, #6 ; store six in R2
16: ADD R2, R2, #-1 ; decrement R2
Line 14 is the only exception.
Impact
Most LC-3 assemblers reject a missing operand separator outright, which would mean the repository's only source file does not assemble at all.
That claim is UNVERIFIED. No LC-3 assembler or simulator is installed in the environment this issue was filed from (which lc3as lc3sim lc3convert lc3tools complx found nothing), so the assemble failure was not reproduced. What is verified is the textual inconsistency with the five sibling instructions quoted above.
Confirmation against a real assembler is requested before severity is settled. If the file does fail to assemble, this defect blocks verification of every other behavioral claim about the program and should be fixed before any of them.
Suggested fix
A single character is added:
AND R0, R0, #0 ; clear R0
The file's CRLF line endings and column-1 layout are to be preserved; the diff should touch one line.
