You can put initialised date in the data section (such as the search linked list example).
To run the simulator, use the command line console (called "cmd" in Windows). Then type "z0 file.txt" where file.txt is your machine code file (called object file). The simulator has its own "command". Inside the simulator type "h" (help) for list of commands. The basic one is "t" (trace, single step), "z 1" turn on trace display, and "g" (go). You can see all registers with "r" and memory with "d address len" (dump). Exit from the simulator by "q" (quit). Here is a sample session with add 1 to 10 program (ex2.txt). We do the first session by running the program in one go, using "g" while turn on the trace display ("z 1").
