I am currently working on the MARIE SIMULATOR and I am attempting to get three inputted decimals, and multiply all of them together. I save my code as .mas and attempt to assemble it. It says I have 1 error but the Assembly listing comes up completely empty! I figured out that the code assembles and runs when I remove the Jump OP from it however, I need the Jump to get the correct answer. Everywhere I look the jump is written as I have it so I have no idea if I am wrong, if my Sim is bugged or what.
ORG 100 /Starting point // Gustavo Brandao. No Partners
Input /Request user input for first number
Store NumA /Store the number
Output /Display number to screen
Input /Request user for a second number
Store NumB /Store number
Output /Display number
Input /Request user for third number
Store NumC /Show number
Output /Display number
Loop, Load NumA /Load the first number, will also loop from here
Add Sum /Add with zero and location which will save the sum
Store Sum /Store the sum
Load NumB /Load the second number for the skip condition control
Subt One /decrement the number
Store NumB /Store the number. when 0, code will skip the jump
Skipcond 000 /Skip when the second number reaches zero
Jump Loop /Used to repeat addition until second number reaches zero
Load Sum
Store NumA /Storing sum in NumA slot to make code easier to read
Loop, Load NumA /Loading the previous sum
Add FSum /Adding previous sum to zero and final sum location
Store FSum /Storing final sum
Load NumC /Second skip condition control
Subt One /decrememting number
Store NumC /Storing skip condition
Skipcond 000 /When the third inputed number is zero, loop will end
Jump Loop /Loops back to second part of code
Load FSum /load the final sum for output
Output /Display final sum
HALT
NumA, Dec 0 /First number; Will be overwritten with input
NumB, Dec 0 /Second number
NumC, Dec 0 /Third number
Sum, Dec 0 /Stores the sum for the first multiplication process
FSum, Dec 0 /Stores sum for the second multiplication process
One, Dec 1 /Used to decrement values
