| seq \- print sequences of numbers |

| prints a sequence of numbers, one per line, from |

| as possible, in increments of |

| for(val = min; val <= max; val += incr) print val; |

| The numbers are interpreted as floating point. |

| Normally integer values are printed as decimal integers. |

| .TP "\w'\fL-f \fIformat\fLXX'u" |

| for printing each (floating point) number. |

| Equalize the widths of all numbers by padding with |

| leading zeros as necessary. |

| Not effective with option |

| nor with numbers in exponential notation. |

| always surveys every value in advance. |

| is a painful way to get an `infinite' sequence. |
