| **Command** | **Description** |
|------|------|
| **Breakpoint Commands** | 
| B\{REAK\} \{program.ext\}\{:location\} | set breakpoint |
| I\{NFO\} BREAK | list breakpoints |
| D(ELETE) # | selete breakpoint # |
| **Run Commands** | 
| R\{UN\} \{cmdlin\} | force debuggee to run cmdlin (at dot prompt only) |
| F\{ORCE\} text | force text (+CR) into target input buffer |
| C\{ONT\} | continue (run) to next breakpoint |
| S\{TEP\} | execute one ASB instruction (step into calls) |
| N(EXT\} | execute one ASB instruction (step over calls) |
| A(BORT) | send ^C to debuggee |
| **Information/Display Commands** | 
| L\{IST\} \{program.ext\}\{:location\} | list source code |
| P\{RINT\} variable | display value of variable |
| I\{NFO\} | display status of debuggee |
| B\{ACKTRACE\} or BT | show call stack (at breakpoint) |
| **Miscellaneous Commands** | 
| WIDTH ### | change display width to ### columns |
| QUIT | quit debugging (debuggee continues running) |
| <Enter> by itself | will typically default to prior command (useful for repetitive commands like STEP, NEXT and LIST +) |
