Hi, below is my code that was written in IDE68K using C. So it coverted my code to asm file(assembly) but my code is jumbled up. Can any fix it. It has no errors but it doesn't display anything. The program is a basic calculator which adds, subtracts,divide, and division. The line that has semi colon in front of it is commented out.
