| *count* |

| *format* |
| can be x (hex), d (signed decimal), u (unsigned decimal), o (octal), |
| c (char) or i (asm instruction). |
| *size* |
| can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86, |
| ``h`` or ``w`` can be specified with the ``i`` format to |
| respectively select 16 or 32 bit code instruction size. |
