option may be followed immediately by a 'd' or an 'f' and an optional |

|
count, which defaults to 1, indicating the number of double or float |
| 58 |
|
binary values to read per record on the input file. |
| 59 |

If the input is byte-swapped, the |
| 60 |
+ |
.I \-iD |
| 61 |
+ |
or |
| 62 |
+ |
.I \-iF |
| 63 |

If byte-swapped output is desired, the |

The |
| 83 |
+ |
.I \-p |
| 84 |
+ |
option specifies "passive mode," where characters that do not |
| 85 |
+ |
match the input format are passed unaltered to the output. |
| 86 |
+ |
This option has no effect unless |
| 87 |
+ |
.I \-i |
| 88 |
+ |
is also specified, and does not make much sense unless |
| 89 |
+ |
.I \-o |
| 90 |
+ |
is also given. |
| 91 |
+ |
With both input and output formats, the passive mode can |
| 92 |

effectively substitute information in the middle of a file |
| 93 |

or stream without affecting the rest of the data. |
