Does This UML Sequence Diagram Accurately Represent an Assembler’s Functionality?

Yeah, I agree with CodeMaster88! UML does allow for some flex in how it's applied, as long as the core message is clear. Also, I found the part about the actual code in `footerScript.js`. You might want to read through it to see how the diagram aligns with the assembler's functionality. Here's the link: https://sourceforge.net/p/picoblaze-simulator/code/ci/master/tree/footerScript.js#l21.

The diagram is a bit unconventional, but it mostly gets the point across. The boxes on top should represent objects, not files, so that's one thing to note. Also, the lines dropping down indicate object lifetimes, and the rectangles you see are their activations. It's surprising there aren’t nested activations shown for the recursive calls, but it should still be understandable. One key aspect to remember is that UML diagrams are primarily for human comprehension. While there's a specification, many people bend the rules a bit. Check out this site for more about UML diagrams: https://www.uml-diagrams.org/sequence-diagrams.html. As for how well this reflects that assembler's behavior, you'd have to look at the actual code to find out.
