Next, using the controls on the main SLIME window, press "Start" to start your program, or "Step" to execute a single instruction. If a run-time error occurs, the OK indicator will change to Exception and the status line will show the exception. You can click on the indicator to clear the exception. ("Reset" will do so as well.)
When your program reads input, you will need to type it in the text field near the bottom of the console window.
If you change the program in the area below and want to load the changed version into SLIME's instruction memory, you can press the "Load" button on the main SLIME window. Or, if you press the "Quit" button, the SLIME window will disappear, and the "Load" button below will once again become active, allowing you to restart SLIME and load a new program in.
This is apparently a known problem in recent browser plugins. See this explanation and fix from Kyle Hatlestad. Alternatively, see the next section for how to run SLIME outside a browser.
You can download SLIME.jar and run it as a standalone application. On many systems, you just need to double-click the SLIME.jar file. Alternatively, you can use a shell command like this:
java -jar SLIME.jar
The "Load" button in this version of SLIME lets you select a file from which to load the assembly code. Alternatively, you can give the filename as an extra command-line argument, as in this example:
java -jar SLIME.jar mySLIMcode.asm
