2 years ago Update on this: I got it to a point where it worked, tweaked it a bit, and now I'm running into a different problem which I think is from the same error. When I don't use any named labels it compiles and runs fine, but when I just make a few of the calls use labels instead of baked-in values it puts the assembled instructions in the wrong place. For example, I have my "main" label set to 0100H, but after it is assembled the instructions following the "#ORG main" directive get put at 0AAA, and all of the other labels are scrambled. The program still tries to jump to 0100H, but the instructions aren't there, and sometimes overwrite each other (I think that's part of what caused the crash the first time). The only solution I've found so far is to just not use labels, which is doable but tedious to work with on larger programs.
Here's the Command Prompt output after restarting the compiler, pasting in my current program, and clicking the autocorrect button.
