    EXAcode for first puzzle:

    -- XA --
    GRAB 300
    COPY F X
    MARK GETDIFFS
    COPY X T
    COPY F X
    SUBI X T M
    TEST EOF
    FJMP GETDIFFS

    -- XB --
    COPY 0 X
    MARK READDIFFS
    TEST M > 0
    FJMP READDIFFS
    ADDI X 1 X
    JUMP READDIFFS

    solution is XB's X register

    ---

    EXAcode for second puzzle:

    -- XA --
    GRAB 300
    LINK 800
    ;//INITIAL SETUP
    COPY F #CMA0
    COPY F #CMA1
    COPY #CMA1 #CMB0
    COPY F #CMA2
    COPY #CMA2 #CMB1
    MARK LOOP
    COPY F #CMB2
    COPY -1 M;//SIGNAL XB
    VOID M;//XB DONE
    COPY #CMA1 #CMA0
    COPY #CMA2 #CMA1
    COPY #CMB2 #CMA2
    COPY #CMB1 #CMB0
    COPY #CMB2 #CMB1
    TEST EOF
    FJMP LOOP
    NOOP;//RUN 2 HERE 4 ANSWER

    -- XB --
    LINK 800
    ;//X STARTS AT 0
    MARK LOOP
    VOID M;//XA DONE
    TEST #CMDF > 0
    COPY -1 M;//SIGNAL XA GO
    FJMP LOOP
    ADDI X 1 X
    JUMP LOOP

    fast-run to the NOOP at the end of XA, then result is XB's X register
