| next | Runs the application program up to the next source line. |
| nexti | Runs the application program up to the next source instruction. |
| rerun | Begins running an application. |
| return | Continues running the application program until a return to the specified procedure is reached. |
| run | Begins running an application. |
| skip | Continues execution from the current stopping point. |
| step | Runs one source line. |
| stepi | Runs one source instruction. |
| up | Move a function up the stack. |
| trace | Prints tracing information. |
