Pops a result off the stack of conditional evaluations pushed by |

.Sx \&ie |
|
and uses it as its conditional. |
|
If no stack entries are present (e.g., due to no prior |

.Sx \&ie |
|
calls) |
|
then false is assumed. |

The syntax of this macro is similar to |

except that the conditional is missing. |

The |

The result of the conditional is pushed into a stack used by subsequent |

which may be separated by any intervening input (or not exist at all). |
