Marie is apparently a teaching language in computer science. There does not seem to be any material available without the textbook.

 

Hello,

I posted some pdf's some weeks ago.
They are in this thread:

OK, here is your source code, re-formatted, with comments.

         Org 100 	// Starting address
         Input 		// Load a number into AC
         Store X 	// Store the AC into X
         Skipcond 800 	// If AC > 0, skip next step
         Jump Else 	// AC was < 1; branch to Else
         Store Y	// Store > 0 value in Y
         Subt Five	// Subtract five from the AC
         Jump Endif	// Exit program
Else,    Load X		// Load X into the AC
         Add Three	// Add three to the AC
Endif,   Halt		// End of run.
X,       Dec 0 
Y,       Dec 0 
Five,    Dec 5
Three,   Dec 3

Does that make the problem easier for you to solve?
Hint:
You are missing an important step right after you store the accumulator into X.
What did you forget to do?
