$1.$ The main code block $($the test harness$)$ will just invoke subroutine $1($LOAD$\_$FILL$\_$VALUE$\_3200),$ and then subroutine $2($OUTPUT$\_$AS$\_$DECIMAL$\_3400),$ using the register value created by sub $1$ to set up input for sub $2.$

$2.$ Subroutine $1($LOAD$\_$FILL$\_$VALUE$\_3200)$: This subroutine will just take a hard$-$coded $(.$FILL$)$ value, and load it into a register of your choice.

$3.($In the test harness$)$ add $1$ to the number and invoke subroutine $2($OUTPUT$\_$AS$\_$DECIMAL$\_3400)$:

$4.$ Subroutine $2($OUTPUT$\_$AS$\_$DECIMAL$\_3400)$: Using your chosen output register from subroutine $1$ as an input register for subroutine $2,$ print the new value out to the console as a decimal number
