## Effect on $X and $Y## 1995 Version of ANSI (Equivalent to Current ISO Version) of Standard |

Below follows a list of control-functions (X3.64) or
__controlmnemonic__s (M) that have an effect on the special
variables $X or $Y or both. Since some definitions
in X3.64 are fairly open-ended, the exact effect may be
implementation dependent in some cases. In section 3.4 these
open-ended definitions are listed resolution of possible
ambiguities are stated.

The relevant __controlmnemonic__s are:

/CBT(n) | $X | |

/CHA(x) | $X | |

/CHT(n) | $X | |

/CNL(n) | $X, $Y | |

/CPL(n) | $X, $Y | |

/CUB(n) | $X | |

/CUD(n) | $Y | |

/CUF(n) | $X | |

/CUP(y,x) | $X, $Y | |

/CUU(n) | $Y | |

/CVT(n) | $Y | |

/HPA(x) | $X | |

/HPR(n) | $X | |

/HTJ | $X | |

/HVP(y,x) | $X, $Y | |

/IND | $Y | |

/NEL | $X, $Y | |

/PLD | $Y | |

/PLU | $Y | |

/REP(n) | $X, $Y | |

/RI | $Y | |

/RIS | $X=0, $Y=0 | |

/VPA(y) | $Y | |

/VPR(n) | $Y |

The control-function REP repeats the previous character or function as many times as indicated by its argument. Hence, the side-effects of this function do not depend on this function itself, but rather on the character or function that is being repeated.
