Debugging a High Level Forth Word

The debugger <Alt+F4> lets you execute the word step-by-step through the original text. You see the return stack in addition to the data stack. -- Demo --  Next

• The steps are executed in the target code - they are not simulated in the host.
• A breakpoint can be set in the current word. You can continue the execution in a subword.
• Flow control structures are traced in the text according to the actual conditions.
• Repeat or skip words in the text: move the marker with the cursor keys to the desired step and continue here.
• I passed the byte $77 to .bin and stepped until swap, then pressed <F3> to step through the subword swap.
