| 45 | * |
| 46 | * ; R0 == pointer to command line in writable buffer |

| 48 | * MOV R1,R0 |

| 58 | * ; R4 == argc |

| 60 | * This routine will handle quoted strings, considering them |
| 61 | * to be single arguments. Either type of quote will do, |
| 62 | * quote doubling is required to insert quotes in quoted |
| 63 | * strings. |
