3113 you may specify a list of variables and @code{load} will only extract\n\ |

3114 those variables with names that match. For example, to restore the\n\ |

3115 variables saved in the file @file{data}, use the command\n\ |

3123 \n\ |

3138 The @code{load} command can read data stored in Octave's text and\n\ |
