 ### Debugging ###
 
-In Logisim there is no way to debug an assembly program in a simulated processor.
-If an assembler is available which creates a LST file of the source code (code address followed by the source code line)
-Digital can view this listing in a trace window with the current instruction being highlighted.
-So the simulator can run an assembly program in a debug friendly single step mode.
-Since Digital has a simple TCP-based remote control interface, also an [assembler IDE](https://github.com/hneemann/Assembler) 
-can be used to control the simulator and load assembly programs in the simulated processor, start the program, perform 
-single steps and so on.

+assembly program executed by a simulated processor.
